It is with pain in my heart that I made a dirty 'workaround'. When the autopilot vertical speed is unequal to zero, it will show VS mode, and when in altitude mode with an autopilot vertical speed equal to zero, it will show ALT mode.
I have to do a few other things and then I'll upload a new version.
