When information is not available in English, the genealogy took falls back to its identifier. All it takes to remedy the situation is to add value by inserting an English label.
In this instance it is all about the Ottoman dynasty and as you can see, Turkish spelling is used in English. The Turkish link for Q6355649 goes to Hümaşah Sultan. That will do as an English label as well.
The one thing I would dearly like is to be able to use the genealogy tool in multiple languages. This is how people can check if labels exist in another language.
