Sounds like your freezer isn’t actually getting cold enough for the ice cream. Semi-melted Tilamook will get whipped-esque if not cold enough. Put a digital thermometer in there for a while and see what temp it’s holding! No ice cream is “drop metal into it and it slides to the bottom” unless it’s not cold enough
As for ice cream consistency, afaik more cream content (which is better ice cream) will be softer at the same temperature compared to ice cream with more water content (shit ice cream). Breyers regular (I think they have a fancy attempt with more cream) is pretty watery, Tilamook is creamed up
(Do you notice a lot of frost on stuff? That is a sign of a bad seal and (humid) air is getting in)
No this is me when someone calls me to ask my plans for the weekend knowing full well I haven’t seen the sun in years
