Amount in Itemized Category Report is different than amount in transaction register (edit)

I've got one entry in an Itemized Category report that doesn't match the register entry and I can't figure out why. For this particular month, there was only one entry for $1,800. The report shows a total of $1,768.88. When I double-click the line in the report (showing 1,768.88), it goes the register entry showing 1,800.00. I've searched all accounts for "1768.88" and have zero results. I'm stumped.
