2. Notice the Maintenance Strategy field is greyed out and not able to change.

The Maintenance Strategy field should be editable only if the task list is not assigned to a Maintenance Plan and Maintenance Packages are not assigned to task list operations. Otherwise the field should be read-only. 

Unassign maintenance package from task list operations will make the Maintenance Strategy field editable again.
