Disappearing Context Column for Grouped Tasks
 

When grouping tasks, why does the option to set the parent task's context disappear from the task list. I can still set it for the child tasks, but for the parent it's as if the column isn't even there. See the attached image for what I mean - where the red circle is, I'd expect to see a text field for setting the context.

Sorry if this is covered elsewhere but I can't seem to find it.

The top level of an Action Group behaves a little differently from regular action items. You can still assign a context to the Action Group (which will become the initial context assigned to new sub-tasks) by using the Info panel.
