Why do I see some taxa in my native language and others in English?

Thre is a Dutch name (and six (!!) english common names but i do not see a Dutch name but happiness do can add the Dutch names
Impatiens https://www.inaturalist.org/taxa/47888-Impatiens-capensis

Also has a Dutch name and i do not see a Dutch name
https://www.inaturalist.org/taxa/159077-Atriplex-littoralis

Has also Dutch name

Ah, i wanted to check on the iphone app, but i only use the app for uploading with wifi so it is nearly always the website. I included a links so i thought it only could be the website. I can use the Dutch names when i want to submit observations on the website.

I do not see the Dutch names for those three species here

Strange, i just checked my iphone6 with iNat app2.7.18 build523 which should not be that old and there the names are shown in DUTCH, i thought they did not 14 hours ago.
