Xcode 4.5 Code Signing Identities say "from '(null)'"

I've recently upgraded to Xcode 4.5, and now all my identities say "from '(null)'" in them when I try to sign for adhoc or enterprise distribution from Organizer:

There is an option to refresh code signing identity which osme times works, but I need to run this every time. The problem I have is I have more than on iOS Team Provisioning profiles from different developer accounts and some times I cannot identify which one is which in terms to sign an adhoc version properly.

Thanks for any help.
