Cannot get rid of purple gift box in Media where images for site are kept

In my dashboard menu options is Media where all the images for my website are kept. A purple square box with “Gift” and a ribbon in it keeps popping up among the images. I keep permanently deleting it, but it always appears again among the images. I also had a blank placement card square that kept showing up among the images, but that is gone for now. How do I permanently delete this purple square? Is this something Square is doing? I use Square as one of my payment options in WooCommerce.
