Thanks but this doesn't really explain it.   I can't find what transactions are causing the issue. 

Let me describe another side effect of this issue: 

Using Fake numbers again:

• If I print a Statement of Cash Flows for 09/01 - 09/30 my ending cash balance is $1,650,000, which is incorrect. 
• If I print a Cash Flow statement for 09/29 - 09/30 my ending Cash balance is $1,000,000, which is correct.  (The $650,000 part of this number is a real number).
• There should be NO REASON why my ending cash balance is different in these two reports.  They both have the same end day.  Their beginning amounts will be different, sure, but their ending should not be. 
• Now, if I keep printing reports going backward one day at a time:
  • 09/28 - 09/30
  • 09/27 - 09/30
  • 09/26 - 09/30
  • etc
• My ending balance stays the same as $1,000,000 until my report for 09/19 - 09/30.  Where it is shown as $1,100,000. (The $100,000 part of this umber is a real number). 
• I thought I had isolated part of the problem.  Whatever $100,000 transaction happened on 09/19 is causing the issue.  Right?  Well, there is no $100,000 transaction on 09/19.  And no, there is not a combination of transactions that add up to $100,000 (There are very few transaction on this day.   I also check 09/18 and no explanation for this $100,000 there either. 

Do you have any idea what can cause this?
