Yes, that is strange. Let us know if it happens again. Verify you are using the lastest version 7.5.3. If not then run software update to download and install it.Was the Transaction Entry report run for "All Accounts" or for a selected account?
Is the YYY-Money Fund in another set of data files?
Was this same report run for the YYY-Money Fund just before running it for the XXX-Checking?
Is the transaction data on the report for the XXX Checking account with just the heading being for YYY-Money Fund?
Since it is printing correctly now I would not worry. Many times there are explainable reasons for why one-time situations occur. But usually it is not worth the effort to find out. But please let us know if the problem reoccurs.
