Missing Geocode search result

Question

I have the following problem on my own site using Mapbox, but I'll use Mapbox's own webpages to explain what I'm facing as I see the same issue there. I use Mapbox's Geocoder example at this link: https://docs.mapbox.com/mapbox-gl-js/example/mapbox-gl-geocoder and I search for 'Feriekompagniet' and nothing shows up. I then click the 'Improve this map' link in the bottom right corner of the map - this takes me to this site: Improve map I do the same search for 'Feriekompagniet' and it finds what I'm looking for (Feriekompagniet A/S). Can anyone tell me what the difference is - how can I get the same search results as on the 'Improve this map' site?

Thanks in advance...
