Text to chapters - compile

Hi Guys
I would like to find out how to compile so that my ‘text’ documents within folders also become chapters when exported to word.

I am sending the FD to an editor and in Scrivener I have the chapters as text within a main folder called A1, A2, A3. When I do a standard compile the individual text documents don’t show as chapters and only the 3 folders show as chapters. What am I doing wrong? Or how do I set the text docs to export with chapter numbers so I don’t have to do that task manually. I am pretty sure there is a way with this great piece of software, if only I knew how …
Thanks in advance
Paula
