Filed against default seems to change on its own
I have noticed that the value that is filled into Filed against changes depending on what user creates the Task. If I create the Task Filed against is set to BAU. Another user gets a result of "Escalated" when using the exact same steps to produce the Task. And on the same project in the same plan. A third user gets a result of BAU like me.
I'd prefer not to set an explicit default. I just would like to know how that default is created and why it is different per user.
