Aaaah... now I see what you mean, unfortunately, these "translations" links are only working with the Title and Description field.
Normally I use the "search phrase" option, put in the English word and let it search on the Dutch language I have. Then I click edit and translate the text.

I did a search on Yes and No but did not find any English yes for the profile field.
The Global yes and no is already translated, so it seems translation is not working for this kind of stuff.
I'm happy most Dutch users do understand what yes and no means, so I think I leave it this way then. Thank you very much for helping me and thinking with me!
