If employee creates expense report with first line as prepaid expense, AWE generates are orphan work

If employee creates expense report with first line as prepaid expense, AWE generates are orphan worklist item in AP reviewer's worklist. Our setup is specifies that AP reviewer should not receive worklist item for approval till all the lines in expense report are fully approved.

When AP reviewer clicks on worklist item -error message says "Transaction is already processed"

This orphan worklist item remains stuck in their queue and we have manually mark to "Worked" in order for it to be removed from worklist.

This issue does not happen with expense report with first line as employee paid.

As anybody faced this scenario?
