Sonuscore The (Complete) Orchestra - output allocation

[JohJoh]

Setting : In this case DAW is ableton live 10, Kontakt 6 player

STCO with a multi consisting of multiple instruments
All (up to 15) individual articulations routed to individual outputs.

After switching off the Kontakt instance (not removing, just temporarily switching off to save CPU), then switching it on again, ALL individual output allocations are lost (back to "default" again).

The problem occurs "now and then" (which is not helping to find the cause ...) , never had the issue with individual instruments ...
