How do I delete already reimbursed expense in Zoho Books?

Hi,
We are cleaning up Zoho Books for new migration of data. The issue is there are already reimbursed expenses that we are unable to delete and this is blocking us from deleting all test projects, test clients. When we try to delete expenses, we keep getting error only rejected, draft expenses can be deleted or we can't delete as it has already been reimbursed. Plus we can't seem to undo the approval the expense or edit that expenses.
Does anyone know how best to delete these transaction? Any help would really be appreciated
