Accounting Entries for Overdue Charges

PS Fin Accounts Receivable 9.2.39

I'm losing my mind. I'm testing overdue charging before we start assessing charges. For one BU when I try to post the charges, I end up with a missing field in the fund code. I thought it should come from the original item, but that's not how it's acting.

Here's the Automatic Entry type set up

Here's the AR_INTERST Dist code

Here's the original item accounting entries

Seems to me I should be getting an accounting entry with a Debit to Fund 44010, Account 124010, but the fund code is blank

I'm hoping that its something that is obvious to the next person who looks at it, but I'm sure not seeing it. Thanks in advance!
