need help!

ok, I installed the WPMU Dev Dashboard and classifieds.
activated both, set up classifieds according to the instructions and posted 1 classified.
after creating it, I clicked view and I can view the classified but if I visit the classified page, its not there, instead it is showing me 2 posts that I had published earlier.

if I go to the classifieds dashboard, I see one of the posts marked as without end date, clicking "end it" doesn't do anything.

if I go to classifieds in the back end, I see the two former posts but not the classified I created.

can someone have a look please? Its a new site and I'm more than happy to give you admin access to solve this dilemma.
