My pints keep on getting scratched.

Hey guys, I bought a Ninja Creami deluxe and I never had any problems with it. I recently bought a New ninja creami (regular version) because it is the perfect size for me. On this smaller ninja creami, I keep getting scratches on the pints and micro plastics get in the ice cream. I have tried flattening the top, and running the side of the pints through hot water, but it still gets scratched. I bought it new for 80 bucks off of someone, so I can’t return it. Does anybody have any other tips on preventing this problem?
