My first app and my first experience with iTunes Connect. I can add and delete users, and assign their roles when I add them, but I cannot edit them once added. The only thing I can do is "Resend Invitation".
I'm logged in as myself with the Admin/Legal role. I have assigned all my other users the "Developer" role. The only Apple ID that is not greyed out in my list of users is my own. If I double-click my own AppleID to edit my roles, I can see that every checkbox is selected.

I've read the above, but it mentions just double-clicking the user's AppleID in order to edit that user's roles an app access. But I can't do that.
What am I missing?
