I have created different Adhoc tasks with function reschedule_or_queue_adhoc_task using same class name, component but different custom data and execution time. I was expecting them to show on Adhoc Tasks list page under different entries but they are all showing up under single entry which was created first with its execution time. In the database the entries are created separately with correct execution time.

According to the function definition, it states:

Only a task matching the same user, classname, component, and customdata will be rescheduled. If these values do not match exactly then a new task is scheduled.

So I was expecting it to list the entries accordingly.
