QBO is not sending a payment event to my webhook

I have a implemented a webbook in my laravel application which received the events from QBO.

Problem

I also enabled the Payment event in QBO, and when I applied a payment to a single invoice, QBO successfully sent a payment event to me. However, when I applied a payment to multiple invoices, QBO did not send any event for it.

Any possible solution?

Below one is the screenshot showing a single payment made for both invoices and event not trigger against it.
