One of those pins should be in the slot at all times. The pins should almost be touching. It looks as if the R-1 shift lever is bent and allowing the pin to ride past the slot at the same time the 2-3 lever pin is past the slot. One pin or the other should be in the slot and both if its in neutral. It looks like you have neither in the slot. Those levers should be parallel to each other.
