Image no longer showing text when hovering over

Hello, 

I added a black fade vignette and a scale animation to my gallery images. I had to add a custom code injection to make the animation work. Without making any changes to the code,  the webpage seems to have bugged out and it no longer seems to work.  The animation still works but the text no longer shows up nor does the image darken anymore.

When I remove the code I added it doesn't revert completely. The text thats supposed to show up is still missing. I have no idea how to fix this. I didn't change anything regarding the text or animation.

I might not be explaining it right but I have two videos, one of it working and another of it at its current buggy state. 

Thanks
