Traktor Kontrol Z2 output issue on deck B

[DJTwenty2]

For some reason when I'm playing through deck B out of my Kontrol Z2 mixer the right speaker volume is low. Deck A is fine in both left and right speakers. Its the same using XLR and RCA outputs, also the same in the headphones. I swapped around my turntables and its still the same so it not a problem with those. Can someone help with this ?

Are the trim levels the same?
