Shrinking images, overlapping thumbnails

Hi there, love the plugin.

I can see this problem has occurred in the past with other users:
https://wordpress.org/support/topic/shrinking-images-2/

Randomly, on some galleries, the images in the masonry layout overlap each other, and when clicked, shrink to a pixel. The scale property shrinks to something like scale(0.00126904) for example, in comparison to a gallery that works correctly which would have a value of 1.

Interestingly, whenever I try recreating the gallery on the page, it still has the same problem. Yet other pages don’t have this issue.

There are no errors in the console, all the code is the same.

Thanks
