Thought I'd report that the language preference question has a bug: you can't deselect a radio button once you select it. That means that if you accidentally select a language you didn't mean to select, you won't be able to remove that selection.
Also, if you try to refresh the page to resolve that, you'll lose your entire progress and need to start the survey again

I've set the question to checkboxes now in place of radio buttons, and added additional instructions. It's a new question, and we'll have to do some work for next year
Ah. Thanks! :)
I've made the changes across all languages
