HSI knob does not work smoothly backwards (freez at 0 deg.)

[YoYo]

When I try to turn the HSI course by knob below zero, it freezes. It stays at zero and can't be set to a lower value, like 350. Only after a certain amount of time (a lot of turning, not like forward) is it able to jump over 0 and go to a value below. This should be rather smooth; turning the knob forward should work the same way backward. Importantly, I use the buttons for this, and whenever I turn it back to below zero, the knob freezes. I'll add a track later.

Thank you.
