Getting Weird Black Rectangle When Placing Tileset

Hi! New user to tiled here. On my first image, you can see theres like these weird black rectangles that seem to be a layer overlap issue. I had downloaded a pack off open game art, its a beautiful pack and as far as i can tell, there really arent issues.

How do I get rid of those black rectangles? Would like to figure it out as I’m experimenting in Iso Game Dev.

Thanks in advance :slight_smile:

Hmm, it’s not immediately obvious to me what could be causing that. Can you link the pack on OGA so I could see if I can reproduce it?
