Xcode 5 Provisioning Profiles Not Available

I cannot access any of the provisioning profiles or code signing identities that I've created in the project settings. It's not that I haven't downloaded the provisioning profiles, or have the correct certificates installed, but there is nothing that appears in the provisioning profile key in the project settings: Again, I have made sure to import the provisioning profiles and certificates correctly. Here's how my account appears in Preferences > Accounts: I'm running out of ideas. I've revoked my existing certificates, deleted all provisioning profiles, and recreated everything again. I also created a dummy project from Apple's included iOS Master-Detail template. That exhibited the same behavior where no code signing identities or provisioning profiles were available from the project build settings. I'm pretty open to all ideas. Thanks. Update As I mentioned, the code signing drop downs don't appear either, even though they have been properly created and downloaded through Preferences / Accounts.
