Record why
Open the invoice, mark it rejected and pick the reason the reviewer gave (missing dates, unclear description, wrong student details and so on). Add their note if there was one.
Fix and resubmit
The invoice shows how to fix that reason. "Fix and resubmit" makes a new draft from the same sessions with your current details, one line per session, and links it to the rejected one so your records show the history.
It gets stricter
After a rejection, future invoices in that program are checked for the same problem before you send them.
