Unwanted “Expand” link won't go away. Can't trace source. display:none; not work

Posting again since the previous topic has been marked [resolved]…

This problem will not go away for me unfortunately. As seen on any product at alcapparel.com:

https://www.alcapparel.com/shop/clothing/looter-crop-tee/

As you can see the word “Expand” is located in the upper left of the product image. I’ve reinstalled the YITH WooCommerce Magnifier plugin, and I can’t find the source of the word anywhere in the files. I’ve also tried hiding it with

.pp_expand {display: none !important;}

but that doesn’t work either.

I’m quite baffled. Please help? I’ve also created an entry for this problem over at StackOverflow:
