KoboCollect for Android and question groups

I have KoboCollect 1.4.8 and seem to be having weird behaviour with grouped questions. When I reach the group, it asks if I want to add a new group (to which I respond that I do), but it immediately takes me to the next question instead of the first question of the group. Is this a known bug and is there a workaround? Is there another app version I should be using?
