Pending notification is not showing in Bell notification if Email notification is disabled

Content

Our overall Notification Mode is 'All', and we need to disable email notification for some certain business process, say Absence. So in the AbsenceApproval task, Tab Notifications, we deleted the rows in Task Status table. Then we don't receive email notification anymore from absence transactions, however, they are not showing in Bell notification > pending notification either....Open the BPM worklist, we can find the notification.

This is not working as we expected. As according to some document oracle shared, the Notification tab is specific to email notifications only. Any change on that should not impact the web notification ( my understanding both bell notification and BPM worklist are in scope of web notification).
