I've worked on these several times over the years (not so much in the past few years).
Be sure you have the turn sig handle on the correct side af the "bendy-bar", stands out as a possible mistake that can be made.
Otherwise, it is difficult to see by the pictures provided just went wrong for you.
Where on the planet is the car at?
EDIT: I just looked at one. Looking through the hole where the handle goes into the column, the white pin is in the back, then the bendy-bar against the pin, then the handle presses against the bendy-bar. The handle pushes on the bendy-bar, not the pin. It is possible to have the handle (or stalk as you call it) between the pin and the bendy-bar which will give you what you seem to be describing.
