Term Store Management - Submission Policy grayed out

In the Submission Policy section, specify whether you want the term set to be Closed or Open. If you want the term set to be updated only by those people who have permission to update managed metadata, select Closed. If you want all users to be able to add new terms to the term set when they update the value for Managed Metadata columns mapped to this term set, then select Open.
