Payee not clear; correct

What causes this issue?

For payment from the one-time account, several items were selected
with different address data. However, only payments with a unique payee
are supported for outgoing payments which include the creation of a
payment form.

System Response

The outgoing payment cannot be posted in its present form.

How to fix this error?

Only pay those line items for which the address data is
identical together.
