SourceTree now shows every branch (even closed ones) when loading up the side panel for a Mercurial repo. My team's repo has 1000s of branches. This makes this latest version useless when trying to navigate a repo. I will have to downgrade to an earlier version cause of this issue.

First saw: 2017-5-5
Happens every time I open source tree.
Unknown if anyone else is experiencing it
Steps to reproduce:
Create a branch
Close a branch
Branch still appears under Branches on the left-hand panel.
Version 2.1.0.2 Windows 10

Screenshot notes:
All highlighted branches are closed
