Seems like solo and routing sometimes doesn't get updated

Hello,

I'm playing around with some drum mixes today. The general issue I'm having is that it seems that sometimes muting/soloing tracks doesn't seem to be doing anything. For instance:

I'm using Superior Drummer3, with multiple outs. I have separate outs for kick, snare, toms, hats, spots, and oh.

I'm playing around with 2 reverb busses, one for the kit and one for the snare.

I mute all the reverb busses. I still hear reverb on the track. Weird.

I disable the bus send - still hear reverb.

I disable the bus send, mute the aux track, and lower the fader completely. Still hearing reverb.

Earlier in the session, I had to completely reload the plug in for this to stop. I rebuilt everything and now it's doing it again.

I'm still not 100% used to LPX soloing behavior (for me, Reaper is much more intuitive here - but it's just bias I suppose). Certainly possible that maybe I'm misunderstanding something. But I've muted every track, I see the channel doesn't have audio going through it, but I'm still hearing the reverb. I'm guessing it's a bug (or I'm going insane! )

Are there situations where the UI lags somehow and doesn't update the audio engine perhaps? Reaching in the dark here, but it seems so strange.
