It seems more like anonymous classes aren't showing up.
The definition in OWL is:
  <owl:Class>

    <owl:equivalentClass rdf:resource="&teams;MixedTeam"/>
    <owl:intersectionOf rdf:parseType="Collection">
      <rdf:Description rdf:about="&teams;Team"/>
      <owl:Restriction>
        <owl:onProperty rdf:resource="&teams;hasMember"/>
        <owl:someValuesFrom rdf:resource="&teams;Male"/>
      </owl:Restriction>
      <owl:Restriction>
        <owl:onProperty rdf:resource="&teams;hasMember"/>

        <owl:someValuesFrom rdf:resource="&teams;Female"/>
      </owl:Restriction>
    </owl:intersectionOf>
  </owl:Class>


Didn't Swoop used to show GCIs?  Would that be applicable here?
