the code above is complete?
every opening tag – needs a closing one – so every <ul> needs a </ul>
but why three lists ?
i guess this will be enough code:

<ul class="icon-bullets">
 	<li class="icon-location"><a href="https://google-maps-link" rel="nofollow">Address</a></li>
 	<li class="icon-phone"><a href="tel:+000000000" rel="nofollow">(+000) 000 000 000</a></li>
 	<li class="icon-mail"><a href="mailto: (Email address hidden if logged out) " rel="nofollow"> (Email address hidden if logged out) </a></li>
</ul>

and:

ul.icon-bullets li {
	list-style: none;	
}

ul.icon-bullets li {
	padding-left: 8px; 	
}

ul.icon-bullets li::before {
    font-family: 'entypo-fontello';
    font-size: 23px;
    font-weight: normal;
    position: absolute;
    left: -6px;
    width: 30px;
    text-align: center;
}

ul.icon-bullets li.icon-location:before { content: '\e842' }
ul.icon-bullets li.icon-phone:before { content: '\e854' }
ul.icon-bullets li.icon-mail:before { content: '\e805' }

with text-align you decide where the icons are in the before containers.

can not test your icon code

sometimes a relative font-size ( f.e. the given settings for screenwidth relation fit well 4vw means 4% of screen width )

if it is only for a few headings – open that page and open that heading ( if the page is made with the advanced layout builder)
Sadly only the other heading styles not the standard style got this option on Style tab to set for 4 different screen width a font-size:

did you check if a different shortcode works on that f.e.:
[av_button label='Click me' icon_select='yes' icon='ue800' font='entypo-fontello' link='manually,#' size='small' position='left' color='theme-color' custom_bg='#444444' custom_font='#ffffff']

if you insert this in the debug field the whole page will be there after saving.

ich sehe du hast es auch ohne script geschaft – muss ich mir anschauen, gestern im schnellen drüber schauen sah ich keine Möglichkeit.
Schau dir aber auch bitte an, wo dein Ajax Suchergebnis Feld landet. Das liegt dann an der flex einstellung das beim Erscheinen der ergebnisse das alles nicht mehr stimmt.

Hier mal meine Lösung :

um ein child-theme shrinking script zu haben – platziere dieses hier in deiner Child-theme functions.php:

function wp_change_sticky_header_script() {
   wp_deregister_script( 'avia-sticky-header' );
   wp_enqueue_script( 'avia-sticky-header-child', get_stylesheet_directory_uri().'/js/avia-snippet-sticky-header.js', array('avia-default'), $vn, true);
}
add_action( 'wp_enqueue_scripts', 'wp_change_sticky_header_script', 100 );

das hier ins quick css:
entferne die obigen Einträge dann wieder zuerst.

#top #searchform  {
  position: relative;
  height: 100%;
  width: 220px;
}

#top #avia-menu #searchform > div:first-child {
  opacity: 1 !important;
  display: block !important;
  max-width: 220px;
  border: 1px dotted #2d5c88;
  top: 22px
}

#top #searchform .ajax_search_response {
  background-color: rgba(255,255,255,0.8);
  position: relative;
  top: 22px;
  border: 1px dotted #2d5c88;
}

#top .menu-item-search-dropdown > a, 
#searchform #searchsubmit, .av_ajax_search_image, .iconfont {
  font-size: 16px;
}

#top .av_minimal_header #s {
  padding: 8px 47px 8px 5px;
}

_______________________
nur zur Info – darf ignoriert werden
wenn du dir deinen Header anschaust, geht der von 88px auf 44px höhe zurück beim shrinken. Das ist normales Shrinkverhalten bei Enfold ( Hälfte )
ich habe mir jetzt die Position des Searchform divs angeschaut und rein empirisch ermittelt: für den Anfang wären ca. 22px top abstand ok – nachher sollten es nur noch 1px sein.
Diese Abnahme des Topabstandes muss ich mit der Variable koppeln, welch die header höhe repräsentiert ( in dem Script ist das newH ).
Mir war klar, dass ich es nur durch Faktoren nicht hinbringen würde – eine konstante musste noch dabei sein.

88x - y = 22
44x - y = 1

zwei Gleichungen zwei Unbekannte
Lösung: x ≈ 0.477 und y= 20

daher die neue Kalkulation innerhalb des scriptes:
search_form.css({'top': (0.477*newH) - 20 + 'px'});

ich hatte noch vor die search results unterhalb mit einzubinden, da die aber noch garnicht im DOM sind wenn die Seite lädt – kann eine ähnliche Berechnung nicht greifen.
– leider –
