Hi,OK... turns out it's actually very easy to fix. In case anyone ever needs to know, you just need to slide the lever over and hold it, while you flip the little plastic doo-hickey to where it belongs. It won't do it on it's own, you actually have to stick your finger in there and push it up. Now, the real question is how it happened in the first place... :?:
I'm having same problem & spouse messed up good side. The lever is the one on top?
