How to suppress "Assign Payment Amounts" pop-up window

When using F-04 to make clearing JE, we have to click on "Accept" on the "Assign Payment Amounts" pop-up window in order to post the transaction. This pop-up window has never appeared in the past. Any idea why this pop-up window is appearing now and how we can suppress it? Thanks in advance.

We did just applied HR Support Packs currently, not sure if that has anything to do with this issue.
