Works great except for uncategorised

I downloaded and installed, after trying many others, as all I wanted was a simple add on to dash menu where I could click, see my posts and drag them in to what ever order I wish. This program appears to do this, but EVERY POST MUST BE IN A CATEGORY as it has no option to select UNCATEGORISED, OK but once done,you reorder your posts and all looks fine until you leave the program interface and go back to your website and NOTHING HAS CHANGED.. off to search for a working plugin to so a simple job.. 🙁
