I believe I know your problem...Look at your other door and use it as reference...the part (i Believe) that you are in ? about it the arm the actual spring goes onto...it just popped and moved on the wrong side of the hinge pin...with a screwdriver get onto that arm and using the hinge area where the pin comes through as the folcrum pry slightly down to move the arm down and push it towards the actual door..it is held againt the inside area of your hinge by that spring that popped...I hope these directions are not too confusing..also as long as it doesn't "pop" again it should be ok until you get that spring back in...
