Web PM - WBS Status

Good evening all,

Seeking to do like in the client where I can change to the WBS layout and using columns, update the project/wbs status per line. In Web PM, I create a activity layout filtered on WBS only and add a column for project status. I get a red stop circle when moving the mouse over the column. (I can't get the red circle in my pic)

I can change in details. Am I missing a field or something?

Thanks,

Patrick
