I have a document in which I customised the heading formats. My work computer had Windows "rebuilt" (presumably similar to reinstalled?) and so the


Word (Office 365) installation is new. But none of that should make a difference because the heading settings are surely stored within the document, right?
I created a new level 3 heading and for some reason it lacks bold. I checked the heading settings and it's meant to be bold but if you look at the document
the new heading clearly is not bold! Thanks for any guidance in fixing this problem.
