Service Desk security access

Using Helpdesk Console 6.5 Supposedly workers can add new queries by modifying an existing query or creating your own SQL expressions. The Clone icon brings up the New Query page pre-populated with the properties of the selected query. This lets you easily create a new query based on the properties of an existing one. When my workers attempt to clone a query they get an error message saying they do not have access to clone a query. All of the workers have level 2 security access inside the helpdesk console. All belong to AD group with local admin access on the server. Where is the security settings for changing queries or being able to post new articles for review in the knowledgebase.
