Issue switching between Bank A and Bank B

Hi everyone!
I’m a noob and I’m trying to use my new minilab on Ableton Live.
I’m using the pads on arrangement mode with a drumrack (using the artura mode in order to use the 8 pads per bank that this mode allows me to use).
Everything is Ok with Bank A but when I switch to Bank B it continues playing the C1 note instead of a G#1 note. I can see the right note on the screen of the minilab but it plays the C1 in the drumrack from Ableton.
I managed to get it to work correctly once but I don’t know how :confused:

Is there any additional setting that I’m missing?

Thanks beforehand!
