Bitrix. Multiple file and fancybox. How to remove looping?

Question

1C-Bitrix

The property is multiple, uploading a video/photo.
If the element is 1 - when there is a loop and it is duplicated 12 times
But if I add the second element - the full order, 2 is displayed, as it should be.
Here is a screenshot, although it only has 1 image loaded.
What could be the problem?
Piece of code:

<?if(!empty($arResult["PROPERTIES"]["OBJ_VIDEO"]["~VALUE"])):?>
        <div class="video">
          <h3>Видео</h3>
          <div class="gallery">
            <?foreach($arResult[DISPLAY_PROPERTIES][OBJ_VIDEO][FILE_VALUE] as $arVideo):?>


              <div class="object">
                <a data-fancybox="gallery" class="gallery" href="<?=($arVideo[SRC]);?>"><img src="<?php echo SITE_TEMPLATE_PATH ?>/img/video.png" alt=""></a>
              </div>

            <?endforeach;?>

          </div>
        </div>
<? endif ?>

Answer 1

Option 1
You are using the gallery tag, perhaps the fact is that you have a slider library connected and it has something like loop, it often does not work correctly when there is 1 element.
Option 2
Make a check possibly return not an array, but a string when 1 element

echo "<pre>";
print_r($arResult["DISPLAY_PROPERTIES"]["OBJ_VIDEO"]);
echo "</pre>";

Answer 2

Andrew, thank you very much for your reply!
But really, maybe there is a loop there and he understands 2 elements how to loop, but one does not?
