xcode validate/submit app has no identities available

I'm trying to submit a mac app store and during the testing/submitting step it ask's for an identity.

My understanding is that this should be the app store identity, however the only option I have availa开发者_运维百科ble is Don't sign.

I have verified that my keychain has both my '3rd party developer application' and the 'Apple Worldwide developer relations certificate authority'. Has anyone else ever ran into this problem? What am I missing?

Apparently there is both a '3rd party developer application' and a '3rd party installation' certificate. I had only generated the one. Once I did the other, things started working great!
