Yeah, a mistake in the automatic calculation on the website was also my thought. Hard to confirm, because the Netherlands is the only team with a 22 point match, but a mistake in counting that extra point (which should of course count as it's a valid point) is the only explanation I can think of.
Hopefully they'll fix it soon.
Edit: now that I think of it, even if they fix it, it shouldn't change anything. Austria has 57, so should be ahead of the Netherlands anyway, whereas Switzerland has 55, but lost against the Netherlands, so should be 2nd anyway.
