Vendor expenses marked as reimbursable

User has set up a vendor expense as non-reimbursable, but upon payment, it's marked as reimbursable. 

In case of vendor expenses, when you pay the vendor bills, the expenses are marked as reimbursable. This is by design and irrelevant for vendor bills. Reimbursements are only applicable to employee expenses to be repaid by the company; thus having vendor expenses marked as reimbursable does not change anything.
