Add MIDI Track Doesn't Work with New Version

[Trailmix]

I open Audio Settings.  Click on "Add Midi Track" and add my VI and MIDI interface.  It all looks right, but it doesn't save or show up.

HELP!!

I have this happen regularly. I usually toggle the midi controller selector and then change to a different plugin and will catch and initiate the plugin and controller to work.  I haven't been able to play through my guitar plugins though. I have reverb on my vocal mic and that works fine, but the guitar passes signal through but nothing from any guitar VST's.  Anyone else have the same problem?
