Description of the problem
We see here that the North Sámi altLabel, vuoiŋŋašhárji, exists:

However, it disappears when we select North Sámi as the interface language. The location of the missing element is marked here with an arrow.

The related concept would be expected to appear at the same place as with other languages.
