AP Outstanding invoices does not cleared

[Janeks Kamerovskis <..hidden..>]

Hi!

I have a problem with Vendor invoices and Payments.

Invoices from one particular vendor after Payments is entered is not
marked as done (still in Outstanding list).

If for other in Invoice payment section there appears only needed record
with paid sum bound to bank account.
Than for those "wrong" vendor invoices there are also record that bound
to costs account with minus, that is without tax. So the result for
invoice is not zero and it is treated like outstanding.

>From GL view all transactions looks just right, I can see no difference
with other AP transactions.

What could be wrong?

brgds &
Thanks in advance,
Janeks
