Content types won't display in Dashboard->All Content menu

I've been fiddling with this for awhile, but since I'm not getting anywhere I've decided to post an issue about it. I have a site with several content types, some of them custom. I've installed the TC Dashboard, and under settings checked which content types I want it to create a menu for. After saving the changes..nothing happens. If I leave the settings on automatic menu creation, it does work for *new* content types I make (I did a test content type) But that doesn't do me any good because I want all my existing content types to show, and recreating them would lose my content.

Any ideas or suggestions? I've tried this in the latest dev version as well with the same results. I have also tried reinstalling the module, and trying out the module on a different site, and nothing is different.

Thanks!
