Duplicate Aux Channels

I am trying to switch from Mainstage 2 to 3 and I am experiancing some bizarre behaviour:

A lot of times when I create aux channels on concert level, they turn up twice on patch level (both marked as concert level auxes). Also the order of my concert level aux channels is messed up on patch level a lot of times and reodrering them on concert level don't help. They are just stuck in the wrong place at patch level. It also seems that when i have several aux channels on concert level that on patch level I sometimes get the same total number of concert level aux channels, but half of them are duplicates that even show up in the wrong order. The other half is just missing.

I have a pretty complex performance patch from M2 that I just tried to open in M3, but I came across this messed up behaviour with aux channels. So I thought it probably has to do with the M2 file format and I tried to recreate the whole thing. But now I am running into the same issue while trying to recreate things in M3. Since I worked a lot in M2 I think I understand the general working and track level hierarchy of Mainstage pretty well. So unless something has substantially changed there this must be a huge bug and I wonder why no one came across this before.

Unfortunately this makes M3 pretty much unusable for me right now. Did anyone else experience this?
