When saving an invoice adjustment for one vendor, a user receives the error "Please enter a valid percentage." The error should not be occurring given the change to the invoice. In some instances, the total distributed at the bottom of the invoice shows as $0.00 remaining. The error is not necessarily legitimate given the input, but the invoice adjustment is unable to be saved when this error occurs.
