How do you check things off on Samsung Fridge Shopping List/Android Smart Life App?

Hey, so I’m feeling really dumb…I can get my shopping lists, but how do I mark something off when I’m at the store? When I hit the check mark circle it gives me an option to delete or edit. I don’t want to delete…I used to be able to just check off and uncheck things as I got them/needed them… I can’t figure out how to check things off on my fridge now either.
