aha – the do_shortcode is the crux – i tried it with tags too and have only the $preview wrapped.
Thanks – but there seems to be an auto close on div wrapping – there are empty divs after the preview insertion.
btw. with p tags it does not work that way

This is enough:

add_filter("avf_portfolio_grid_excerpt", function ($excerpt, $entry) {
    $id = $entry->ID;
    $preview = get_post_meta($id, '_preview_text', true);
    if ($preview) {
        $excerpt = "<div class='av-custom-grid-excerpt-container'>" . do_shortcode($preview);
    }
    return $excerpt;
}, 10, 2);

thats nice – because it is much easier to style this preview text than the excerpt field.
is it possible to add in this case a custom class to f.e. the output div grid-entry-excerpt entry-content ?
because f.e. ul’s do not have in that case that enormous line-height. And it is easier to select with a special class.

in text elements – the inserted image floating left got a class: alignleft

you can increase the default value from 10px by

#top .avia_textblock img.alignleft {
  margin-right: 40px;
}

lists in text Element – or lists from advanced layout builder element ?
Can you show an example page?

see here an example page – and code how i did that.
In principle, I misuse a specially uploaded iconfont for this (e.g. 3d-icons) – and then replace the monocolour icons with the coloured ones using css.

However, I have made a little more effort and uploaded monocolour icons of the coloured ones to fontello, so that I can see in the icon selection what kind of icon I want to use.

hm – on functions-enfold.php line 827 i found the orderby : post_date
and the filter avf_post_nav_loop_args – but have no success with post_title

PS: du könntest diese svg auch zu fontello.com hochladen, und so dir ein eigenes fonticon set machen.
die svg sollte man jedoch zuvor zu einem compound path vereinen ( Illustrator alles auswählen dann : Objekt – Zusammengesetzter Pfad – erstellen )

lade dir das zip mal hoch unter : Enfold-Child – Import/Export – Iconfont Manger
https://webers-testseite.de/manfred-ergott.zip
Dann hast du den Satz als Iconfonts zur Verfügung.

Try first only my solution without redefining the featured image source – this will only use a different image-size source for that featured image.
And because masonry image-size is a non cropped size – use that.

btw: on your copyright link in the footer you have made some mistakes.
i would only insert that line:

© Copyright - NSW Dowsers Society. All Rights Reserved. 

and add to my child-theme functions.php:

function new_backlink(){
	$kriesi_at_backlink = " - <a href='https://xfactadesign.com' target='_blank'>Xfacta Design</a>";
	return $kriesi_at_backlink;
}
add_filter('kriesi_backlink' , 'new_backlink');

or maybe clearer in that way:

function my_own_backlink($link){ 
  $no = "rel='nofollow'";
  $slogan = "Website Design by - ";
  $theme_string = "Xfacta Design"; 
  $backLink = "https://xfactadesign.com";

  $link = "{$slogan } <a {$no} href= {$backLink} target='_blank'>{$theme_string}</a>";
  return $link;
}
add_filter( 'kriesi_backlink', 'my_own_backlink', 10, 1);

that snippet set the new value for the backlink. in this case you do not need to add the shortcode [nolink]

Nun bei deinem Nick ist es allerdings nicht allzuschwer die Domain zu finden.
Eventuell ist die Einstellung: Dashboard – Enfold Child – Allgemeines Layout – Fixiertes Seitenleisten-Menü : “Fixieren, wenn Seitenleiste kleiner als die Bildschirmhöhe ist, ansonsten scrollen”

nicht uninteressant: so bleibt dann dein Menü sticky – und man muss nicht ellenlang scrollen um wieder eine Auswahl zu treffen.

try:

#top  .av-large-testimonial-slider .avia-slideshow-arrows a  {
  top: auto !important;
  bottom: 0px;
}

masonry image size is a non-cropped size too. ( or use full images )
so – if you use that snippet in child-theme functions.php it will use that image-size format:

function av_remove_featured_image_link($image) {
    if (is_single()) {
        $image = get_the_post_thumbnail( $current_post['the_id'], 'masonry' ); 
    }
    return $image; 
}
add_filter('avf_post_featured_image_link','av_remove_featured_image_link', 10, 1);

this should work too on category basis:

function custom_avf_post_ingnore_featured_image_link( $ignore_image_links ){
  //  e.g. available variables
  global $avia_config, $post_loop_count;

  //  no image links on posts inside a given category 
  $ignore_image_links = in_category( array( 1, 'grafik' ) ) ? true : false;
  return $ignore_image_links;
}
add_filter( 'avf_post_ingnore_featured_image_link', 'custom_avf_post_ingnore_featured_image_link', 10, 1 );

what version of Enfold you are running?
there is more support on cpt in the newest version

Have you also defined a custom taxonomy for your CPT?
Do you use a plugin to register the CPT?
