music in iclouds

I see this question quite a bit but can't find one with a response from Apple. Does anyone know what is going on with music in icloud? When the new updates came out for music in the iCloud over 200 of my songs duplicated and greyed out with a cloud next to it. I've searched the internet and most people are saying its a glich. Is this the case, is there a solution other than deleting a lot of music, is there a fix coming? I know its not my computer because my music in iTunes was perfect and synching just fine with my other Apple devices. Does anyone know what is happening with this?

Thanks
