Summary: When I try to plan a task using the P shortcut. If I try to mention the time slot with a different start time. It does not actually add it to the time slot instead it adds it as a task on top of the time slot.
Replication steps:
  1. Create time slot on your calendar
  2. Create a task and use the P or shortcut for plan.
  3. Type in your time slot name and a time for the task other than the start time of the time slot. (ex. Work Hours at 11:30 AM when your time slot starts at 8 AM)
  4. The task will appear on top of the time slot instead of inside the time slot.
