BR: Rack multi out systematic Crash

[asprog]

Hello,
I made some track presets with Ujam drum plugins wrapped in multi out rack (it's not a submix track, just a folder track)
- I create an empty new project,

- insert my preset,

- delete my created track,
- insert again the same preset or another of the same kind. So the newly created track is not organized as it should,

or sometimes

- try to drag the called "master" track to rearrange as it should be => crash instantly!

Same if I insert my preset in an existing track...

Many thanks to look at this
