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

14hours ago i thought the name was in english but now 14hours later it is in Dutch on my iphone which has a Dutch language. The iphone Inat app is also in Dutch but i changed my website in English to understand the forum much more, the Forum.inaturalist.org is hard to understand if you do not have an english app or website version.

I saw both English and Dutch names and was surprised to see a Dutch name present on the Taxon page…(and now also Dutch in the iphone app)

This is a photo from the website and i was able to enter the dutch BOSDROOGBLOEM to change Linaria to Gnaphalium sylvestris.
