Can`t delete "Titles" and "Departments"

Can`t delete "Titles" and "Departments"

I can not delete the created value "Titles" and "Departments". Error - Removing Unsuccessfull. The values ​​are currently in use! But the value is not used anywhere, I created it a few seconds ago. "Offices" and "Companies" - also can not remove the existing and new values. Super administrator rights, database MSSQL.
