Undo & Q-Link Issues with faders

I keep having undo issues when working with the faders. Undo will skip undo steps especially if I type in a value number on the fader. It also will do some weird things if I go from balanced to stereo panner to A/B the sound difference. If I am in center panning, when I undo, it may go hard right or some other parameter that I did not select or have even used.

With Q-Link for selected multiple tracks, sometimes it works, and sometimes it does not. I will select Q-Link and it simply will just not work, or if I have tracks selected and type in or pull down 0.2db or another value, one track may go down 0.2 db and the other some random number like 1.7 db. It’s really making it hard for me in the mixing process having to monitor or redo, undo, etc because of these issues.
