 - According to the `specification

   modalities should not include their AET name in
   ``ScheduledStationAETitle`` on user initiated queries.  Therefore,
   they do receive worklists that do not concern them. This may be
   handled by the ``FilterIssuerAet`` configuration option. Note that

-- Orthanc 1.2.0 does not handle the ``Generic group length`` tags.  
-  You might need to include this kind of :ref:`lua script <lua-fix-cfind>` to remove these tags from the queries::
