Unable to rename Groups in NLS (channel or bus) *intermitent

After not using this suite of plugs for a while I’d like to start again. I’ve opened up an old Logic file and started inserting NLS instances, but no matter what I can’t rename the groups (rename “Group 1” to be “Vocals”, etc).

I’ve just tried the same process with brand Logic session and got the same results EXCEPT after multiple attempts on Group 8, all of the sudden it activated and I could rename. but not after that and again, not with any other channels.

My guess is that is is going to be a V9 issue, but if anyone has any other thoughts, I’d love to hear them.

Thanks!
