Quicken 2016 Reconcile Not Working

Quicken 2016 running under Windows 10 does not reconcile accounts correctly.  When you try to check or uncheck a transaction in the list displayed by Quicken, the balance does not update.  Sometimes if you exit reconcile and enter again, it will update.  Sometimes clicking "Mark All" will help.  But it doesn't work correctly.  The Quicken community says this is a known issue, but has not been fixed, yet.
