Cloud Snc Issues - Duplicate Playlists

My tracks are stored on a USB Drive plugged into my laptop

I also have the 5TB Dropbox Cloud Storage with Rekordbox Pro Subscription

I created a series of playlists in Rekordbox and drag/dropped my tracks from USB drive into the corresponding Playlists, organised by Genre

Afrobeats 

Electro 

Dubstep

Etc...

Once all of my tracks were in Rekordbox, I then enabled Cloud Sync in Rekordbox Settings

After a day or so I noticed that I had a whole other series of duplicate Playlists...

Afrobeats (1)

Electro (1)

Dubstep (1)

All of my playslists are now duplicated with the original playlists, plus these others with (1)

It's very off putting

How can I fix this?

I"m obviously doing something wrong

Your advice appreciated

Thank you
