Bill Pay Set-up Problem

I have encountered a problem that is preventing me from setting up bills.  When I enter the pay amount for the bill, and then drop down to the line item area to add the expense account details, the figure I entered at the top of the bill does not drop down to the transaction line where you enter the expense account to pay from.  When I manually enter the amount that is an exact match to the amount entered in the bill area at top, the system still tells me the amounts don't match so it won't let me process the bill so it can be set up for cutting the check.

I rebooted my computer, but the erroneous error message still  comes up preventing me to finalize the bill to get it paid.  I've used QB for over ten years and have never had this problem.

Any suggestions?
