Receiving money on a sales invoice form prefield with negative value

When I click on receive money on a sales invoice, and then select the ‘received in’ cash account the form gets filled with data and the ‘unit price’ and ‘amount’ are in negative.

I’m fairly sure that this – number in negative – did not happen before. I can manually remove the ‘-’ sign to have the correct entry.

Am I looking at a bug? Or am I doing something wrong?

what version of Manager are you using?
try updating to the latest version and see if the problem is still there.

I was using [17.6.10].

You are right, after updating to 17.7.57 the problem is gone.

there are always updates which are not announced that would fix most bugs. so the first step is to update to the latest version.
