Trouble asigning audi channels external mix mode

Today i installed the latest version of traktor on my brand new Mac m3 pro using native acces, i am using an Audio antelope Orion gen 3 mixer and a model 1 mixer, connected to the thunderbolt port, al fine , audio interface comes up and i can assign the first 10 channels, 1-10, as soon as i try to use 11-12 and higher traktor crashed, tried to use the Orion interface in usb mode same issue and then i reverted back to my old windows machine, same issue !! tried the previous version of traktor, no issues at all so seems to me there is a bug in the latest version in combination with my hardware setup , any ideas ?

The latest version of ableton has no issues what so ever both on windows and the mac with the audio interface
