Refresh Serato Library
Try to import a previously added crate to EP. The import as crate option is greyed out.
Say i added a few new tracks to my Serato Hip Hop 2019 crate this week. This crate was created first week of January and previously added to EP as crate. So in both tabs EP (collection and serato) you can see this crate. Some reason i cant seem to re-add the crate to reflect new tracks.
