Hum... I'm not sure what is happening.
Is the 'slider bar' the object on your profile page that lists your most recently updated lists? That object only shows about five of your lists and only the ones that you have recently updated.
If you go to the tab at the very top and click on "My Stuff" and choose "Lists" it should show you all the lists you have created. I see 6 Semi public lists and 8 Public lists. Is there something missing from this area?
I thought it might have been an issue with some of your lists being set as "Mature Content" but I changed my settings and nope... same amount of lists show up ether way.
