I have been using QB 2013 for Mac since January of 2013. When I reconciled my checking at the end of March 2015 and all the months before I was in balance.  I have been using Quicken since 1991 and this is my second time using QuickBooks. QB seems to have an issue. The March Reconciliation Summary balances perfectly with my bank statement. And all others before that. Nothing is unclick, deleted.  I go to the balance at the beginning, when we started the business, which is .00 in my bank ledger, but when I run a report it says I have $28,121.86 as a beginning balance.  This all started when I went to reconcile my April bank statement.  The beginning balance is off.  This is definitely a QB problem.  But I don't know what to do about it.  Very frustrating.  Can anyone help me?
