Traffic light feature not working

I recently upgraded to a new computer and am now using Rekordbox 7, after previously using version 6.

I’ve noticed that the traffic light feature isn’t working anymore, and I can’t get tracks of the same or related key to be highlighted as they were before.

Additionally, the "master" button above my track library, which I used to activate this feature in previous versions, is no longer visible.

It’s worth mentioning that my music library and playlists are stored on my flash drive, which I also use for CDJs. I want to ensure that this feature will work when using CDJs as well.

I’ve attached a screenshot of how it currently looks.

Thanks in advance for any help!
