Photo gallery problems

Hello! I have a problem with my theme and the image galleries. The images are not displayed until you descend to the footer. By chance I noticed that if I add “opacity: 1;” to the second div the problem is corrected.

<div class="entry-content photo-content">
<div id="gallery-1" class="gallery galleryid-30030 gallery-columns-5 gallery-size-medium" style="position: relative; height: 2341.02px;">
<figure class="gallery-item" style="position: absolute; top: 0px; left: 0px;">
<div class="gallery-icon landscape">
all the images
</div></figure>
</div>
</div>

<div id="gallery-1" class="gallery galleryid-30030 gallery-columns-5 gallery-size-medium" style="position: relative; height: 2341.02px; opacity: 1;">

But I can’t find that div in the templates. Can help me find that template? ??
