[Almost Solved?] 2017.3 Can Not Display Multiple MIDI Tracks In PRV

I must be missing some new element?
 
I previously posted regarding the lack of Pick Tracks in PRV, but now I discover that I can't seem to display multiple MIDI tracks in the PRV by any means. I also tried via selecting multiple MIDI tracks before opening PRV as I often have.
 
I also played with the new auto lock button in the Track Panle, but only one (the same/single one) is all that will display.
 
Thanks
 
Edit:
 
OK... I think I got it. Disabling Auto Lock then Selecting all three (currently 3 chosen) displays them. So this replaces the pick Tracks option I guess?
 

Hi Keni,
Granted, I haven't done that much with it in the last 24 hours, but as best I can tell it's working OK here.  I have a project with about 15 MIDI tracks and they all display in the PRV track list.   Do you have of the the filter thingies on the right side selected or or otherwise?   I'm still coming to grips with how that works.
