Mine just looks weird and then leaves that residue. Didn't change coffee and have gone through several cream cartons and it doesn't seem to matter whether the cream is fresh from grocery or been in fridge for a while.
Just FYI, we were at one of the breakfast joints we went to before COVID-19 and the server brought a little old lady eating by herself a dish filled with the little creamer jugs. She said something to the server, who then picked up the dish, left, then returned a few minutes later with 1 of those metal serving containers with the spout and lid, which obviously had something cold in it as there was condensation. Sure enough, what she poured into her coffee was either milk or half-n-half. So ask if you don't want the nondairy stuff.
