Since we started working with JIRA, while planning our sprint, we could filter the backlog to by users using the little icon in the top. When we did this we only saw the tickets the person is assigned. In the last 2 months this functionality has changed and now when we filter for a particular user we now see subtasks. This is usually when the main task is assigned to another person but their input is needed and a single subtask is assigned to them.
We do not want this as it causes confusion during the planning process. How can I turn off this "feature" so that it looks like it did for a couple of months?
