B3102270 writing wrong Account ID

We have AAI's set up to catch items account ID's when entered against Work Orders.  We have a Catch All set up for when an item is not set up correctly.  We find the item when it goes to the "Catch All" Account, fix it and it then falls to the correct Account. Occasionally, the item falls to the wrong Account and it appears to be set up correctly for the AAI's to use.  Has anyone else experienced the issue, when using the P31113, that the Item you are issuing goes the wrong G/L account for no apparent reason?
