Problem displaying two galleries in one post

Hi,

thank you for creating this amazing plugin!
I have an issue with displaying two galleries on one page – first one works like a charm, but the second one won’t show up. The second gallery has images (aka not empty).
Var_dump informs me that the second gallery is an empty array.

The code for the first gallery is

if ( $images ) {
    foreach ( $images as $image ) {
       		$id = $image['id']; // The attachment id of the media
            $title = $image['title']; //The title
            $full_image_url= $image['full_image_url']; //Full size image url
            $full_image_url_square = acf_photo_gallery_resize_image($full_image_url, 300, 300); //Resized to 262pxw 160px h image url
            $url= $image['url']; //Goto any link when clicked
            $alt = get_field('photo_gallery_alt', $id); 
            
            echo '<div class="col-xs-6 col-md-3 col-lg-3">';
            echo '<a href="' .$full_image_url . '" target="_blank">';
            echo '<img src="' . $full_image_url_square . '">';
            echo '</a>';
            echo '</div>';          
      }
      }
echo '</div>';

and the second (practicaly the same with renamed variables)

$timages=acf_photo_gallery(tehnicna_galerija, $id);
echo $timages;
var_dump($timages);

echo '<div class="row">';
if ( $timages ) {
    foreach ( $timages as $image ) {
       		$id = $image['id']; // The attachment id of the media
            $title = $image['title']; //The title
            $caption= $image['caption']; //The caption
            $full_image_url= $image['full_image_url']; //Full size image url
            $full_image_url_square = acf_photo_gallery_resize_image($full_image_url, 300, 300); //Resized to 262pxw 160px h image url
            $url= $image['url']; //Goto any link when clicked
            $alt = get_field('photo_gallery_alt', $id); 
            
            echo '<div class="col-xs-6 col-md-3 col-lg-3">';
            echo '<a href="' .$full_image_url . '" target="_blank">';
            echo '<img src="' . $full_image_url_square . '">';
            echo '</a>';
            echo '</div>';          
      }
      }
echo '</div>';

Best regards
