Divi issue on hover

Hi, I hope you can help.

I think this is a compatibility issue with the Divi theme which I am using.
On the url I have attached, you will see that when you hover over a product image that has a badge on it, there is a white bar under the image. Other images that do not have a badge are fine. Is this a Divi issue or can you help?
Thanks
Ilana
