Format Data Table Dynamic Range Not Working!

Hi,

I am not sure why dynamic range is not working with the Graph ----> Format Data Table ----> Label Option --- > Select Range --- > Values From Cells 

I am trying to use dynamic Range as defined in the name manger as "Roof_Outbound_ID", for some reason I am getting a warning "The Reference is not Valid"

Is it allowed to use a dynamic range in the label option for graph!!

Could you please clarify.

Please find the attachments.

Thanks.
