Unable to add on OS role with access role for COmputer set to Change.

 I have granted permission to help-desk users to the  computers tab  with Details and Roles set to change. They are able to add a computer but when trying to add an OS role they receive this error "You don't have access to the requested information. Please contact your Administrator"

any ideas how to get this to work with out giving them full admin rights.
