There is a link from the admin section back to the links home. I followed the link you provided and it looks as though you still have the alpha installed there. Notably, a first clue to me was the number of links in the main cats is not displaying. I added this to the latest release and even though you may not have a link in the main cat, it will still count a 0 and display it next to the cat name, just like the sub cats do.
