Trouble grouping pans in 5.1

[stefanboman]

Cant seem to get pans to group properly in 5.1
I´ve made a group linking all the pans on all channels. I want to shift all the tracks a bit to the rear speakers.
Many channels follow the pan link(like expected), but some channels won't.
Can´t see any logical reason for it. Can´t see any pattern in which channels doesn't follow.
If I shift the left channel to the rear speaker on a stereo channel, most stereo channels(left) shift back but not all.

If I attention the channels that doesn't follow the pan, then the panning seems to follow.
But does not work if I select all channel.

Really annoying bug, and time consuming.

Anyone encountered this or found a way around this?

Confirmed bug. I have a case open with Avid for over half a year. No progress. They're currently still at the stage trying to reproduce it themselves. In my case, happens with LLM enabled and HW inserts active.

Great feedback! Thanks.

I also have hardware inserts.
I´ll try without them.
