I have some playlists that seem to be imported in reverse order when exporting from Mixo to Engine DJ.

#1 in Mixo becomes #14 in Engine DJ, #2 becomes #13 etc.

This doesnt always happen though.
I have the issue of scrambled playlist order in the past even, but I cannot seem to be able to replicate it now.

If you mean playlists (not playlist tracks), please add a new playlist to the top of your list in MIXO, which will force-update the order numbers for all playlists below, then export again and it might be fixed.

You can do this for any folder, or the root.

For any playlists with incorrect track order, move the last track to the top of the list, then back again and it will also force update the order and correct any undefined values.

Let me know how it goes!
