Outstanding Deposit on account reconciliation summary, but no outstanding deposits in my next months bank reconciliation screen

I am trying to track down an amount showing on my "Account reconciliation Summary report. Report by statement end date." 

outstanding deposit - 6,741.20 yet when I open up the reconciliation & deposits for my next month, there are no 'outstanding' deposits for the month prior to be cleared off.  how do I figure out where this amount came from.  I can not drill down in the report to bring me to the entries.

Thank you for your help in this matter.
