Missing dynamic pages in the list of the links

I have a list of product groups which, by clicking on it, should link to the products in that group.
But when I want to link (on click on image for example) to the dynamic page “Producten Producten”, this page does not appear in the list. There is only 1 dynamic page appearing, although I made 3 dynamic pages.

See screenshot.

Any idea what I’m doing wrong?

Thanks!
Frédéric
