How do I get the Group layout on the data tab in Chart Expert to be available?

I have all of my charts in Report or Group headers.

I don't understand why it is not available.

My chart in the Report Header has the Group layout available and is being used. 

If it is available there, why not in the rest of the charts?


Thanks
