Hi,
SAP will not show invoices which are to paid through payment run combined, as it is the way for the user to check all the invoices which are to be cleared in the payment proposals. (I suppose the screenshot which you have provided is related to payment proposal list).
However, when you make the payment, unless and until you make necessary settings to post all the invoices individually, SAP will not post them individually.
This might answer your question.
Best Regards,
