If you have multilang labels in a feedback activity multiple choice question, the result graph and result table in the App do not respect the multilang filter in their labels.
Have almost two languages installed, e.g. fr and en.
Have multilang filter activated.
As teacher, go and make a feedback activity with a multichoice question having a choice label including multilang (I went and modified https://qa.moodle.net/mod/feedback/edit.php?id=18&do_show=edit to have the multiple choice answer <span lang="en" class="multilang">good</span><span lang="fr" class="multilang">bon</span> instad of 'good')
As student, fill out the feedback form.
As teacher, in the app, go and see the result clicking on the pie chart and looking at the underneath table.
