Comment 3 for bug 871954

OK, it is not a bug.

What you have to do:

In the credit line you have to change the proposed amount of 0.00 to the amount which is credited.
Then you have to change the Amount Paid to the NEGATIVE value of what was proposed.
As a matter of fact, you have to add everything you received and SUBSTRACT everything which was paid.
(But this is a credit payment remember?)
The resulting amount has to be entered as Amount Paid.
When you make an error here (paying the customer something for which a credit invoice doesn't exist,
or the total amount changed on the bank account does not match the total of payments and amounts
received, there is no such thing as a warning.

So it is not a bug, it is an awkward and confusing user interface.
I could finally grab it, I don't think my customer ever will.
On top of it, this is non-documented.
