Images do not have transparent backgrounds for collections - Dawn Theme

Hello, when I add collections to my store the collections get rid of the transparents backgrounds, even if the images are supposed to have them. How do I fix this?

Hi @Dogg ,
This is Theodore from PageFly - Shopify Page Builder App.

The photo with you has a white background so it’s impossible

Theodore, currently most of the images do have the white background, but when I tested it with transparent backgrounds it wasn’t working. Similarly, you chose a single item when specificially my question is about collections.

I understand, I tried that and it didn’t work with the collections. As you can see there are single items with transparent backgrounds.
