Safari session issues on the Manager

I'm using Safari 7.1 and I can't seem to stay logged into Linode Manager.

I can log in, I can use my two factor ID, I click "remember me", but about 50% of the time I click from page to page it completely blitzes my session.

I know cookies are enabled.

I know my source IP address is not changing.

Anyone have a clue? It's very annoying.
