In Oracle Fusion Collections, when we complete task, updated strategy tasks are getting assigned

Hi Team,

I have a Strategy Method "Key Customer" (with tasks Phone Call 1, Phone Call 2, Phone Call 3, Phone Call 4) in my system already.

I have a delinquent customer where already this Key Customer Strategy is assigned and Phone Call 1 which is first task in Wait Status.

Now, there is a requirement to include Dunning Letter 1 task to this method at starting, so we have updated this Strategy Method accordingly.

Now, Strategy Method looks like "Key Customer" (with tasks Dunning Letter 1, Phone Call 1, Phone Call 2, Phone Call 3, Phone Call 4).

At the moment, I did not run any collection jobs.

When I opened above mentioned customer site in Collections and completed the first task i.e. Phone Call 1, I see Dunning Letter 1 task is assigned and is in Wait status before the Phone Call 1.
