M.C. 8.6.5 Bug - Media Creation Settings Reset

I have encountered a solid bug with the new Media Composer 8.6.5 software on a Windows 10 PC.

In a 29.97 UHD project, the Media Creation setting resets to LB resolution each time I open the project. I have to set it to SQ before I start working each time.

I will submit as a bug report to Avid.
