We have been experiencing issues with the search results showing all items in calendar view. We have noticed about a week or so ago that not all tasks in a saved search would show in the calendar view but show completely in the list view. This calendar view is very critical for us as a time to filter out assignable actionable tasks that are usually subtasks of larger tasks to showcase daily/weekly actionable items for our team. We also review this daily with the team.
As you can see in the example we have individual assigned tasks that are tagged by the type of task. The list view over the 2 days has much more than what is shown on the calendar view.
