3rd level sub categories not showing up in main menu

hi there. So, my site is https://foodifylife.com/
I am having issues with my 3rd level sub categories not showing up in the main menu of my page.
example:
in the menu in the edited form it has

-for the love of food
–basic cooking ideas
—4 bean salad
—egg sandwich

but when I go to my site and look at the main menu, “for the love of food” is there and so is “basic cooking ideas”, but NOT “4 bean salad” and “egg sandwich”.

Any ideas on how I can get this to show up on my main menu bar?
Thanks so much! I appreciate your help!
