New Logic 10.3 update is great except for Track Alternative bug!

Disappearing Track Alternatives
The new Logic 10.3 update was unleashed last week and we love it…kind of. It's overall a fantastic update and introduces a bunch of new features. A favorite new enhancement is something I've longed for since I "switched" from Digital Performer to Logic many years ago; The ability to make another underlying "playlist" ala Digital Performer or Pro Tools. Apple calls this feature "Track Alternatives". Unfortunately theres a big bug whereas when one does an edit to the top most "Track Alternative" track, the hidden Alternatives may disappear. The work around is to always show the hidden Track Alternatives while doing any kind of editing. In the long run this isn't very practical so I'm hoping that this gets fixed in the next update. I made a video documenting this bug and hopefully will prevent others from losing too much hair over this issue.
Update: As of the latest 10.3.1 Logic X update, this bug has been squashed!
