How to edit the username of a saved Remote Desktop connection in Windows 10?

I want to change it. Clicked on the [...] button. Chose "edit".

Ask me every time
foo

are my choices. I click on "foo" to edit it. It is read-only.

I tried deleting the saved desktop and recreating it. Windows 10 remembers the name I want to edit.
