Image Occlusion not displaying correctly

In the document, i have multiple image occlusions on multiple images. However, they do not display correctly until i hover the curser over them.
It seems like the image occlusions on the image i am hovering over is applying to all the other images in the document, which is not correct.

I also got a problem with a lot of flashcards with image occlusion that are empty image in the queue…

Please fix it asap, ty
