Beat grids being overwritten when running "Add New Analysis Data"

Hi,

I just upgraded to rekordbox 6.6.1 from 5.8.6.  Everything imported fine initially.

But when I load a song to play, its beat grid and BPM data is getting overwritten sometimes - I'm guessing this is because "Add New Analysis Data" is being run on tracks when loaded for the first time.  I also tried manually selecting running "Add New Analysis Data" on some tracks, and beat grids and BPM are modified occasionally.

All of these tracks have analysis lock turned on.

- Should "Add New Analysis Data" be modifying data for songs that have analysis lock on?

- Am I going to have to suck it up and check/edit the beat grids of every song again?

I see this mentioned in the 6.5.0 release notes as being fixed, but it sounds like this may be the same issue: https://forums.pioneerdj.com/hc/en-us/community/posts/900002013026-rekordbox-ver-6-5-0-has-been-released-Jan-28-2021
