I've set my browser languages to "English (US)" first, and "Dutch" second. Instead of showing me the English-language version of the site, I get an absolutely atrocious auto-translation into Dutch instead (barely intelligible; way worse than Google Translate would produce).
Why are you even looking at my language preferences if you don't respect my preference, of getting English first? And maybe don't do secondary languages if you haven't done a tiny bit of quality assurance on the translation?
Likely a mismatch of the type of English, if the site treats only EN-US (or EN-UK) as english and hasn't included the other, which would just be a mistake.
Then it might switch to your second preference. Alternatively if your device OS is set to dutch, or have some language system like a virtual keyboard or input manager set to dutch, the site might look at that over the user-agent? Very odd choice if any of those.
