Cc121 solo function won't release project solo

Steinberg Hardware
1

Solo and mute buttons are not behaving the same as a mouse click.

  1. Select solo midi track 1 with cc121.
  2. Select solo again with cc121 to release solo on midi track 1, however the entire project is still muted.

If I do the same with a mouse, then step 2 unmutes entire project as expected.
