PO Authorization Rule for only Specific Supplier Stat Group

I am trying to activate an Authorization Rule for Purchase Order for some specific Supplier Static Group.
I selected all Usage of Authorization Rule except Apply Regardless of Supplier Stat Group and put values in the Supplier Stat Grp tab which I want to include for this rule to have under authorization rule.

Please follow the below screenshot for reference as I set up my rule.

Can you please help me out of this to make the rule which will apply only for Supplier Stat Group.

Thanks
