Include in Manuscript

I am about to compile a manuscript, but when I check my work I see that I cannot check the box for “Include in Manuscript” for the chapters. The scenes are checked, but not the chapters, and I cannot highlight this feature to make changes? What am I doing wrong?

They have to be inside the “Draft” folder for this to be available, as it is the Draft folder that gets compiled.
All the best,
Keith

Got it. Thanks for the quick reply.
