Change single image problem.

click only color (not other variations) change image function doesnt work for me. I set it correctly (auto detect variation image).

I am using Fancy product designer plugin. This function is not working with it: https://bikafa.com/tisort-tasarla/

But its working without that plugin https://bikafa.com/gamer-tisort-uniseks-the-monster/

How can i fix this? It is very important for me.

Thank you.
