I’ve always had an issue with the way the global master section operates. Because of this, I’ve made a workflow using the Audio Montage mode that saves all plugin settings in the montage session file, the way any other DAW would work.
If you can use a montage and not use the global master section, you might find everything easier.
There are a few plugins that are only available in the global master section unfortunately, but not many. I’ve found a way to avoid it all together.
