FaderPort - enable solo on selected folder

I have set up the FaderPort to navigate between folders (containing tracks in the Project window) in Cubase.

My issue now is that when I jump form folder to folder, the solo on enabled folder does not follow the folder I choose, like it does when I jump from track to track.

Also the Solo and Mute buttons only work on tracks, not folders.

I have activated: Enable solo on selected track.

Does anyone now how to solve this?

Best regards,
