Action Center defaults to Manage Actions - so 'assign to myself' isn't available

I don’t understand why if Manage Actions is selected and I click an Action, I see “Assign to a user” at the top and have to manually pick someone from a pulldown…but when My Actions is selected there is directly an “Assign to myself” link at the top.

There shouldn’t be any difference in presentation of the Action. It should be the same no matter if Manage or My is selected.

Even worse, after doing the “Assign to a user” it just kicks me back to the list instead of keeping me in the Action. So now I have to go find it again.
