WsSQL - GetDBMetadata does not list superfiles

GetDBMetaData via WsSQL don't appear to return superfiles in the metadata even when selecting for all metadata to be returned.

As per attached example, all metadata information is being requested:
<IncludeTables>1</IncludeTables>
<IncludeStoredProcedures>1</IncludeStoredProcedures>
<IncludeTargetClusters>1</IncludeTargetClusters>

However, all files in the metadata are returned with <IsSuper>0</IsSuper> and the superfiles we know exist in the cluster (e.g. reed::in::sf::account, reed::in::sf::novaauditlog, etc.) aren’t listed at all.

Example log attached showing GetDBMetaData but no superfiles being returned.
