Why does Credit Hold Batch show orders placed on hold which have not been placed on hold

In JDE Oracle E1, 9.2, I have run the R42542 Credit Hold Batch program and noticed that the report shows numerous orders (not all of them) as 'Order Placed on Credit Hold'.

When looking into the customer services screen, the orders are not showing any credit hold codes and the orders are not in the release credit hold screen.

So, although the orders appear on the report as if they have been placed on credit hold, in the system, they actually have not.

Secondly, the customers for these orders have no credit limits set, so they should not be shown on the report as placed on hold.
