I'm no expert but it appears to me that you're simply having a problem by having both accounts going at once.. one thing to try, be sure you're logged in for the profile editing under the same account as for posting.. it's two separate logins so that could confuse things a great deal.
I say this because I'm currently having to re-login for each session if I want to post, but it's remembering me in the profile editing part, so they are separate.
