Image Occlusion not working properly

I’ve installed the Image Occlusion Add-On, downloaded and created a few cards, but it always shows everything on the front of the card.
So theres the picture with the Masks, the mask alone, the ID, the picture without the mask and the solution instead of just the masked picture.
It’s the same if i download card or create them myself.
How do i fix this?
Thanks in advance
