Syncing iPhone 5S causes iTunes match issues
I have my iPhone 5S (iOS 7.0.2) set up to sync to my iMac (13,2 running 10.8.5) for backups, photos, videos, and apps. I have iTunes Match enabled for music and iCloud enabled to sync contacts, calendars, notes, etc between various iDevices (another iPhone 5s, two iPhone 4, and an iPad 3) and my iMac. Last night I connected my phone to my iMac for syncing I have come back to find that about 75% of the music in my iPhone playlists show up as needing to be downloaded from Match.
I checked, and every affected song that I looked at was still on my phone but now has a locally stored version and a version with the iCloud symbol next to it. Downloading all the "missing" songs in a playlist doesn't work. As soon as the song has completed downloading the iCloud symbol returns. I confirmed that the playlist doesn't see the songs already on my phone by turning on airplane mode. The songs in my playlist with the iCloud symbol next to them then disappear.
I would really appreciate any suggestions for how to resolve this problem.
