I noticed that in CHT 4.x, if you select an option, go forward with the flow and then decide to come back, some questions that can’t be deselected, e.g. select ones in radio buttons, they will still be selected.
So if you go past a radio button question, then go back to correct something, or even in the same page, and this radio button disappears, questions that have this radio button in their relevance will still be shown. Is there a way to clear radio buttons or avoid this behaviour? I think on CHT 3.x it was different (could be wrong)
