I’ve got it.
Ableton does export it as an stereo track .. So i deed also pan it in there hard left and right..
So when making an new multitrack and dragging the left channel in there, I deleted the second one.. Also did this to the right channel but there I need to delete right channel1 (u follow?)
So with this knowledge I can perfectly work (don’t know if this is called an workaround?)
Thanks for your help …….
Newbie @ the utrack buttons B-)
