Serato Crates Lost

I tried to merge an old Hard Drives Serato Crates with my current one and have lost some crates. However they are stiol showing on my Lexicon app. How can I get the crtes on my Lexicon app back to my Hard Drive?

You can Sync them to Serato. Go to the Sync page and put it on “Playlist” and then choose the playlists you want to sync to Serato, they’ll become crates there.

I’ve tried that but the crates aren’t syncing bk to serato. I can see them on lexicon though, but the files that were in them are not showing

Are the tracks all in Lexicon and working properly?
