owl:sameAs not showing up in my instance of query service

[Lhaaits]

I'm running a docker instance of wikibase and wdqs according to the wmde docker-compose file (with customization).
I've added WikibaseRDF extension and have gotten it to work locally. As in, I can create mappings to urls for entities.

However, I do not get any results if I search for

PREFIX owl: <http://www.w3.org/2002/07/owl#>
SELECT ?item ?itemLabel ?itemDescription  ?object ?objectLabel ?objectDescription WHERE
{
?item owl:sameAs ?object.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}

or any owl:sameAs result with this one:

select * where { ?a ?b ?c}

auto suggest does recognize owl:sameAs though...
Am I missing anything?

I have this in my localSettings.php:

wfLoadExtension( 'WikibaseRDF' );
$wgWikibaseRdfPredicates = [
    'owl:sameAs',
    'owl:SymmetricProperty',
    'rdfs:subClassOf',
    'rdfs:subPropertyOf',
];

I have the same issue, the mappings appear in the RDF over at Special:EntityData but it never becomes available in WDQS/BG. No obvious errors in any logs.

Is other data defined via Wikibase RDF showing up in WDQS/BG? In other words, is it just owl:sameAs that is missing?

On my end all mappings created by WikibaseRDF ends up missing while other data is updated correctly.

Example RDF: https://wikibase.wbworkshop.tibwiki.io/wiki/Special:EntityData/P36.rdf

I wonder if this could be caused by the RDF types having two nodes about each direct prop? Thus the updater skips the one from WikibaseRDF given it could look like a already processed node?
