High lipase milk?


I’ve been feeding my girl frozen milk from my stash to try to rotate it and I’m afraid that o have high lipase milk. It doesn’t taste...great (granted I’ve rarely tasted my fresh milk) and my girl isn’t finishing bottles, which isn’t like her at all. She doesn’t seem grossed out or act like it’s yucky, she just will stop being interested in drinking any more and leave about an ounce left. Does this sound like I have high lipase milk and she’s not liking it? I’ll be super disappointed bc it’ll ruin my plan of trying to pump until I have enough milk for a year.
