Google Music. Snogs on device Appear twice

[Timelessblur]

Ok my problem is any song I have on the device appears twice when I am showing music from the cloud.

I use double twist to sync my favorite stuff to my device (5 gigs out of my 35gig library). Now anything double twist syncs it appears on my phone but as soon as I say show me my cloud stuff it pretty much doubles (one cloud one local). This drives me crazy because if I want to listen to a certain artist everything is in there twice and it messes it all up.

It is almost like the meta data is some how messed up but I have not changed anything locally.

Some help would be great.
