Problem inserting posts via wp_insert_post()

Hi,
I need to insert posts from outer source into my Enfold website using wp_insert_post() function.
I wrote a script that creates posts, and inserts some ALB shortcodes as content.

Here is my PHP code:

—————————————————–

$post_arr = array(
‘post_content’ => $my_ALB_shorcodes,
‘post_title’ => $my_title,
‘post_status’ => ‘publish’,
‘post_type’ => ‘tribe_events’,
‘meta_input’ => array(
‘_aviaLayoutBuilder_active’ => ‘active’,
‘_aviaLayoutBuilderCleanData’ => $my_ALB_shorcodes,
),
);

$the_post_id = wp_insert_post( $post_arr );

—————————————————–

So basically what I do is insert some shortcodes in each post ‘post_content’.
Please note that post type is set to ‘tribe_events’ because The Events Calendar by Modern Tribe is installed and I’m actually creating events.

Now everithing works fine except for a little issue: the posts show some layout problems on front-end.

The strange thing is that the post layout in back-end is perfect and layout problems disappear if I save the post.
It looks like saving posts fixes their layout.

I enabled ALB debug mode to check if the content in the post back-end do actually change after saving, but it is exactly the same.

So I took a look at wp_postmeta table in DB.
I found “_avia_builder_shortcode_tree” and “_alb_shortcode_status_content” new rows in wp_postmeta DB table after saving the post.
It looks like they contain serialized data that are inserted after saving.
Are that rows relevant for post layout?

Any help?

Thank you
