Update existing member shows "Username is already in use"

Hello,

I’m trying to update an existing member, but when I save the member I get the following error: “Username is already in use”. The Username/Login field is not updated. I checked the cmsMember table, but the LoginName is only there once.

I haven’t reported this as an issue because it only happens for 1 specific member. So I first would like to check on the forum if someone else experienced this before. We’re using Umbraco 7.4.3.
