Hi Jim,

Unfortunately, this is a known limitation of using custom sorts with the Group Role. It is documented and listed as the second bullet under the Using a Custom Sort section: For graphs, a custom sort does not work if the data item is assigned to one of the legend data roles (either Color or Group). The same restriction applies when sorting on the raw values of a data item that has a user-defined format.

Thank you,
Teri
