For some reason the URL for SIteLink's is always null.

varentity=newEntity(_wikiDataSite,"Q1022");awaitentity.RefreshAsync(EntityQueryOptions.FetchAllProperties);

I also tried around withEntityQueryOptions e.g. setting onlyFetchSiteLinkURL and so on, but I couldn't get it working. Is this a library Problem, or has it something to do with the Wiki-Site I'm querying? (Wikidata)
