Every other database on the instance behaves, and the server-level <code>max degree of parallelism</code> is where it should be. The cause sits one level down. Database scoped options show up only in <code>sys.database_scoped_configurations</code>, as <a href="https://learn.microsoft.com/en-us/sql/t-sql/statements/alter-database-scoped-configuration-transact-sql?view=sql-server-ver17">overrides to server-wide default settings</a>, and <code>sys.configurations</code> shows server-wide settings only.</p>
