AP Invoice with additional posted values

I am not great at understanding the accounting aspects of AX but will try to explain best I can. I cannot make sense of what happened with this transaction/payment. Original invoice of $34.41, the AP check was $34.41

Voucher for APInv-025441 - $34.41

Voucher for APPay01125 - $40.61? $6.20? – I cannot understand where these numbers would have come from?
