AP Bill Balance is Zero in the line but invoice is open when the pay by line is ticked. Bill does not to show up to apply

Hello,

I have an AP Bill which pay by line is ticked. The Bill has been reversed and the debit adjustment is created.

Then I’m trying to apply it against the bill by the payments and applications from. Since it needs to be applied with the type payment, The payment type is selected and the Debit Adjustment is loaded in the line. 

But The bill does not show any available balances to apply. But the bill is still open, the lines show the balance to zero. There are no any other applications as well.

I tried to recreate this but I could not recreate this as well. is there any specific reason for this behavior. 

Thank you
