I work a lot with Sub Crates in Serato. When I Open Rekordbuddy I See only Folders with no crates and Tracks inside when i click on the tree in Serato.
Some Folders/Sub crates are totally missing.
And the First Letter of Every Sub Crate is missing.
I testet it with normal Playlists without Sub Crates, then it works.
Maybe its a bug? Because the 2.0 Version of RB works fine and i changed anything in my Library.
I hope we can fix it soon because now i can not sync From Serato to Rekordbox
