Traffic Light function on USB playlist

I have made and exported a playlist to USB in rekordbox. All songs have been analayzed for key, bpm, etc. in both my collection and on the USB.

When I mix this playlist from my collection I have the option to select the Master traffic light feature and see which tracks are compatible with my currect playing key. When I mix from the playlist on the USB though, I don't see the traffic light option, but I do see all the keys.

What do I need to do to be able to see the compatible tracks on my USB instead of having to use my collection? Or is this not possible?

I am using Rekordbox 6.1.1 on Windows 10.
