What makes you think they are part of the package. AFAIK you cannot package roles.
They are not listed as available:
Components Available in Managed Packages
Items referencing queues and roles also cannot be included in a managed package
References to a specific user in workflow actions, such as the email recipient of a workflow email alert, are replaced by the user installing the package. Workflow actions referencing roles, public groups, account team, opportunity team, or case team roles may not be uploaded
and for queues
List views associated with queues cannot be included in a package
Special Behavior of Components in Packages
So I do not believe that they are able to be in your managed package
