Can't use Habmin2 Graphical rule editor, please HELP

I have recently started using OpenHab2 to make my DIY smarthome but i found it rather difficult creating the rules, thats why the graphical interfase is there right? to make it easier… But i can’t seem to figure out how to use it. I create what rule i want in the graphical interfase and when I want the code to paste it via ssh, the ode isn’t there. What can I do, is it broken, Am I doing something wrong?
Also i cant seem to be able to edit any of my items, the say error 404 or 405 (item not editable).

Any kind person that could help me, I would really appreciate it. Thanks Ivan
