Added to cart pop up is covered by product photos. Help please!

[AMBP]

The added to cart pop up for some reason is behind the product photos. Things to note:

• It only seems to happen on products with additional photos (more than one photo per variant).
• It only happens on mobile.
• I attached a photo of what it’s supposed to look like and how it’s appearing instead. 

Please help if you can! Help is greatly appreciated. Americanmadebaby.com
