Hi @Kristiansen, Håvard ,
Built-in policies sometimes have different limits than custom policies. The limit on policies per policySet was increased to allow users to duplicate large policySets but it looks like now the parameter limit has been exceeded as well in a policySet that users want to duplicate. So we will open a task to increase the parameter limit to match what built-ins allow. In the meantime that policySet is a built-in policySet that is already available for any customer in the portal so you do not have to create it yourself.
