profile manager drop ios 7 devices

Just updated a couple of my ipads to ios 7. Installed profiles from profile manager no problem.

I then enrolled the ipad, enrolls fine. I went to do the next one and the first one had disappeared from profile manager. But if you go to the myserver/mydevices on the first ipad, it says its still enrolled.

I have just looked under completed tasks and have found "wipe ipad has succeeded" for the ios 7 ipad. So it looks like after a certain time period it removes the ipad. But all the apps and settings are still on the ipad except the remote management profile.

Has anyone else had this issue?
