This is more of a general Windows administration question and not directly related to Bvckup 2. If it were my setup, I'd probably either:
(1) investigate what this second session is and where it comes from, e.g. by using "net use" command from an elevated Admin prompt. Clearly, something has changed in your environment, so trying to go through recent changes would be another thing to do.
(2) just forcibly close that session by using appropriate Logon/Override combination in the share credentials setup window - https://bvckup2.com/wip/05042016-2
Though #1 is a more kosher thing to do, because #2 may end up breaking something other part of your setup.
