BFD 3.5 alt key bug in groove editor multi-toggle mode

In Pro Tools 2020.12.0 (Win 10), alt key not working in groove editor and groove lists. In groove editor the following bugs exist:

  • Multi-toggle mode, Alt+L does NOT work when trying to draw in a drum hit
  • Multi-toggle mode, Alt+R does NOT work when trying to erase in a drum hit
  • Pressing Alt to selct a drum hit and drag to copy does NOT work
  • Pressing Alt along while using the mouse scroll wheel to zoom in/out does NOT work

And in the groove list and groove arranger:

  • Ptressing Alt to drag a drum groove to copy does NOT work
  • Pressing Alt along while using the mouse scroll wheel to zoom in/out does NOT work

I should note that the above bugs are not evident in the standalone app, just not in my version of pro tools.
