AI Music Editor Loses The Edit

I'm not sure how/where to report this, or if it's already been mentioned, but I'm having an issue in Studio v20 Beta 3 where I'm using the AI Music Editor to extend or shorten a track (awesome feature BTW - thanks for this!). but after exiting Resolve, then starting up again, the clip is red and there's no music there. I now have to find it i nthe media pool, re-add it to the track and go through the adjustment all over again.
Is this a known issue? Is there a preventative action I should be taking (other than rendering it to a file) or some remedial steps I could take to recover it after restarting?
