Agree with Ryan. Check those forks and particularly how they are attached to their "rails." My check would be to place the top in 3rd gear - then remove the top WITHOUT Jiggling, and by pulling directly "up" - then see where the 2nd Intermediate/3rd gear sits with respect to the input shaft - which you can see right there on top.

There are those detent balls and springs and rail grooves which you can check the action. There should be decided "positions" as you stroke the gearshift lever.

You want to continue disassembly and check that the original assembler hasn't done something like use two of the incorrect slider rails together. Per Don Snyder's most excellent description:

The shafts in the tower of the transmission that the shifting forks mount to. A-7240 (R & 1st) has the 3 detents equally spaced, A-7241 (2nd & High) has 2 very close together and 1 near the end of the shaft. USA.
