References to obsolete roles in Process Configuration Source

Not sure if this is a bug, but I was looking through the Process Configuration Source associated with a project that is based on the latest version of our standard process template and I see references to roles that no longer exist (in addition to the roles that do exist). For example, we have eliminated the following roles yet each still has a block within the team-configuration->permissions section.

team
permissions
role id="Product Owner"
...
role id="ScrumMaster"
...
role id="Stakeholder"
...
role id="Business Product Owner"
...
role id="Analyst"
...
role id="Architect"
...
role id="Administrator"
permissions
...
