Crazy default behavior for Quick Add, "Choose Options" pop-up

[Platypyrus]

I am using the basic Dawn theme. I am editing my collection template and using the "Enable Quick Add Button" feature. When I test the page, I see "Choose Options" buttons since there are variants. When I click that button, I get a large square pop-up that is mostly blank, the product image is shoved into the upper right corner, and the title text is gigantic. 

Why is this the default design and how do I modify it?

Hello @Platypyrus 

Please share the concept or idea of the design you want, and I will create it accordingly. You can provide specific requirements such as color scheme, layout, and any content you want to include. I’m ready to modify it as needed!

I just want to know where I can edit this section.
