module shows category that is not there

I've installed beautiful ck and it seems to work. I wanted my blog categories to show, and on some pages it does and on other pages it shows a different category which I did not define.
On this page: lifecoachutrecht.com/index.php/workshops/familie-opstellingen you can see on the left side, "blog onderwerpen" and underneath "Nieuws". On the other pages as defined you see all the subjects ("onderwerpen). While if you look at the homepage their is how it should be. How come?

Hi
have you set correctly both modules as described in the doc ?
look in the forum, it is explained too
