Q: Reverb plug ins track through Patches when I need them to change!

Hi, I'm trying to create different patches containing different reverb sends as I've done a million times before, but when I change the plug ins ALL the patches change to the new plug in selection. It's driving me crazy. I need to have separate plug ins in each different patch.

Is there a box I'm not checking? Lite version of MainStage? I'm on MainStage 3 - El Cap 10.11.15

Cheers
