Using headphone on Nord Rack 2

[Klein015]

Hi,

I am using the Nord Rack 2 with a headphone, and in Program Mode, I only seem to hear the program stored in slot A. Whatever other slot (B,C,D) I press, I only keep hearing slot A. So also layering different programs is not possible. However, in Performance Mode, I do hear all programms in the 4 slots.
Am I doing something wrong, or is the headphone by default only outputting slot A in Program Mode? If yes, can this be changed somehow?

Thankx for you help in advance!
