I am looking at a backlog board for a new Kanban style project we created. In the Epic list it has a % complete for each Epic, but it doesn't match either the number of issues or the % complete for the epic's children.
The Epic in the epic gutter looks like this:

but the children of the epic look like this:

The only other "Done" category status is a "Done" status that I do not have any of the children of the epic in yet.
With this all said, I have made many changes to the workflow in the last several days and it is very likely that some of the stories were once in a "Done" category status but now are not. Is the % complete stored as a state and not calculated real-time?
Thanks,
Steve
