When i try to export to Traktor, in the playlist select menu i dont see the playlists i ve got... I see playlists that i deleted and i dont have right now in MIXO...

I have raised an idea about the deleted playlists showing in the list:

I can see the scrollbar in the export popup window, were there any of your new playlists showing up further down or was it all old ones?

Yes there where my new ones with the old ones... Correct

Great! So the idea to remove deleted playlists is accurate, thanks for confirming!
