It sounds like you have the preference on the Home Page Local Options (gear icon) for
Open Plug-Ins on Workstation When Knobs Assigned set to Expand Fader Module, which you don't want. This is going to always favor the Multiband when you attention a track. Try setting this pref to
1st Expand Knob Module (Pro-Q2 will open) or
2nd Expand Knob Module (Pro Compressor will open). You should also be able to set it to
Master Module and still be ok.
