Hmm. I actually corrected the spellings two days ago, so I'm wondering why people are still seeing the old ones now. Caching must be involved, but accessing the website in a private windows shows the correct spellings to me.
I see now, there should be a redirected to a new URL, but it only works as a logged in user. I'll have to check that out... Next year.
They managed to spell it three times correctly. Unfortunately, one of the two mis-spellings is right in the title:-(
