Celebrity description language in Azure Video Analyzer for Media

We’re testing Azure Video Analyzer for Media. I’ve posted several video clips with the language set to Norwegian (nb-NO). However, when I examine the celebrity description in the celebrity detection window as explained here, the language might be French in some situations, Turkish, English, or Norwegian in others. What factors influence the language used in celebrity descriptions? Is there a parameter I can change?
When I browse the results for a specific clip and select Translation: Norwegian, I receive the description in Turkish. When I select Translation: Swedish, it is in English. This issue persists regardless of whether we use the portal or the API (using widgets to display the results).
