Problem:
they fill in 'Yellow' on the product page and add it to the cart, it's translated to 'Geel', which is Dutch. Text fields should not be translated when customers fill them in.
Solution:
"Default" is a fallback text domain and it will translate the strings on your Website that matches the translation. It's the "nl_NL.mo" file on the server "/wp-content/languages" folder as shown in the attached screenshot. Removing that file should fix it.
