Received not Invoiced doesn't match GL

The report “Received not Invoiced” has always not matched the AP clearing account. But the difference is very small. After an upgrade from E9 to E10.2.600 over the last few months, it has been off significantly - the GL account is higher than the report. The amount keeps growing bigger.

I’m not sure if this is due to the upgrade or not. Can anyone please advise how should I check this issue? Is there any query to run?
