Polar alignment confusion

Hi All

Last night (early this morning) I was setting up a Nexstar 4 a friend kindly gave me.

1: I set the wedge (see photo) to my latitude (35 degrees south).
2: ensured the bottom mounting plate was level (using bubble level)
3: faced the wedge due south (using compasse)
4: Set the scope to point inline with the fork (see photo)
5: Looked through the dot finder expecting to be near the pole (see photo)

What happened next is confusing:

I expected the scope to be pointing at the pole (roughly).
It was way to high (10 degrees to high).
I had to adjust the wedge a wopping 10 degrees to get the pole star in alignment.
This meant the wedge angle was 45 degrees (instead of 35(my latitude)).

I don't get it.
