My Ro Go is working now and I get some extremely high scores so it rolls over two or three times. I am not that good but the scoring goes to quick. I think the setting is wrong.

At the backbox the number of balls is set to 3 balls, but I get 5.
At the backbox there are two plugs in the score, I think that should be only one?
In the bottom there is also a setting for the number of balls, but I don't know which one is the plug.

And two off-topic questions, where can I find the plastic to fill the hole in the playfield and the covers for the coinbox?

(Edit, sorry somehow the pictures come out rotated)
