Adding payment amount

I'm adding a full payment amount but only a partial payment is being entered, and not adding $1.00 I've tried doing this about 10 times and have the same result. I add in an additional payment of $1.00 and then it subtracts a dollar saying I still owe $2.00 quite frustrating. 

Angie, can you please share some screenshots of what you're exactly doing?

For sure. I get different results even thouh I have entered payments the same way each time. 
One registered as paid, but the others say partial even though the amount is full. Am I doing something wrong? And then only that one gave me the weird descrepancy.

I can confirm this happening, only in "Expenses" - "Bills" though. In "Incomes" - "Invoices" it works as expected and says "Paid". Only Bills always say "Partial, although on the bill info page it says:

Total: €0,00

And above that it says Paid: xxx (the amount) and that corresponds with the amount that it should be. So something ain't right in this section for some reason.
