Neundo Buss insert not working with plugins

Hey Everyone got a bit of a snafu.Doing a mix routed all vocals to a buss but here is the kicker, tried to put a plugin on the insert it was greyed out trying to take it off it wouldn’t let me.Never saw this issues.Any thoughts??

Constrain Delay Compensation turned on by any chance?


That be it! I was fortunate to hear back from Greg last night.Thank you so much, I had one of those “Ah Duh” moment lol :man_facepalming:t2:
