Keystation 61 MK3 Pitch wheel seems to be offset?

I’m not sure if anyone else has fixed this problem before, but the neutral position (when you don’t touch it) of the keyboard seems to be offset down a step like this:

It also takes a considerably longer distance to go up than going down physically. It feels like the encoder is offset, but I’m not sure at all.

Does anyone know why this happens?
