I tried to modify some question and answer pairs and notice that the interface has changed considerable. Actually I don't have a clue what to do anymore.
Does anybody know how to change it back to how it was. I can't find an option to change the interface.
I tried to find ways to reset\change the interface or find documentaion why it has changed but did not fund anything.

You can delete the existing and upload the docx that you are referring.
