Hi John,
1.- You write "I can remember if I had enabled content AND headings in my remote server, but I have now." I suppose you mean "I can't remember etc."
2.- I've clearly told you that you SHOULD NOT use any multilang filter in the Question names! It will not work. And it serves no use, as the question names are not displayed to the student/end-user.
3.- I know about the display problem of both French and Canadian French, which has been discussed here: https://github.com/iarenaza/moodle-filter_multilang2/issues/25 But in your case you don't need to use fr and en, just use fr_ca and fr_en, that's all!
4.- Now to come back to your orignal problem, you don't say if it has been solved by my last post. If you enable both content and headings in the multi language content v2 filter, does that solve the problem, i.e. are now the draggables choices correctly displayed according the current user's selected language, en_ca or fr_ca? If that's OK, then we can close this discussion.
