Crossfader bug or faulty Kontrol S4Mk3?

Enso

The crossfader enable/disable status isn't remembered on exit app.

If I disable crossfader AB and CD on gui, when re-open application, Crossfader A and B back to be ON, desired behaviour would be stills disabled.

Edited: I suspect my Kontrol S4-Mk3 have some kind of issue on crossfader front selectors, because A and B selectors don't change settings on gui and feels different on move than C and D. Maybe this make Traktor re-open with crossfader A and B always on? anyone have the same behaviour? It's possible to force crossfader A and B always stays off even if S4 is faulty?
