Mixbus 32c busses solo problem

[eliternity]

Hi everyone. I need any help :
In my my mix I use a differnt bus for keys , gtr, bass, drum. 
When I solo any bus I also hear the other instruments while they are not assign to that bus.
Ex: I solo bus keys and I hear drums, guitares and bass too...
Someone could tell me what's going wrong?
Thx Elie.

Shot in the dark, but for me, soloing a track or bus includes any key track(s) (e.g. tracks feeding sidechain compressors) affecting the solo'd stuff.

Hi Elie
If you send all the drum tracks to a "drum bus", you must disengage the master send knobs on all the drum tracks. I think you did that.
Check what solo option is set in the preferences. (picture)
I use solo override mute. good for listening to references.

I remember there used to be some solo issue with the buses 9-12 but had been fixed some versions ago.
I would do a test in a new  experimenting session with few tracks and sending only one track to a bus and see what it does when the bus soloed. 
Then it is easy to follow what changes in the setup results in
