When you push shifter, number 2, red bit moves round, cable and casing isn’t visible and the whole things remains shifted round. No other mechanism works. Does that make sense?
yeah, makes sense. but still looks like the red bit has broken. Kind of looks like it's rotating too far
try putting a cable in there, pulling on it so it has some tension then spraying the whole thing with lots of WD40 and pulling on the cable while downshifting.

Before shift and after shift
