Header font

I’m not sure when this issue cropped up for me, but when I go to the compile window and edit my format, I get the following screen, showing that my header should be 12 pt TNR.

However when compiling, it gives me 12 pt Helvetica.

What other step do I need to take so this compiles the way I’ve set it?

Many thanks!

Make sure you haven’t set a global font override in the main compile overview screen (top of the Layout assignment section). With that setting enabled, none of the font family settings will be used from the format itself.
