Secondary image appears on top of main image

Hi, for some reason after a few plugin and theme updates the plugin woocommerce image product flipper stopped working as I intended it to.

Here you can see where the plugin should be working: https://promagicstore.com/product-category/playing-cards/

Basically when you hover over the product images the sceondary images should appear nad the main image dissapear. Although the secondary images do appear, the first image should dissapear but it does not.

Any help on how to make this secondary imnage dissapear would be welcome!
