When we set up during our last trip, our back bunk bed - the right bed pole back saving slotted support wouldnt "click in". The left side did, but not the right. We've brought it home and set it up again. Still the slotted support will not click in place. We didn't use the bed end when we were camping - and haven't put any weight on it since this happened. Do we need to replace the whole bed support pole? We shouldn't use the bed until both bed poles click in place with the slotted brackets, right? We have the king size Niagara beds. Not sure why the one side won't "click" in place and not sure if we can fix the part or need to replace it?
