Hello @Aussiesj,
In 4.16 theme version Menu options were moved into popup https://image.prntscr.com/image/5yXyaVh9QG_srPw4jpVEdw.png so to be able to see all menu settings, you need to click on “8Theme Page Options”.
If this is not what you are looking for, please, provide some screenshots for better understanding.
Regards
