Adding a Page on WordPress Not Working

Hi,

I am working on my company’s Website, but cannot seem to add a page to the menu bar (the page does work). I have been using WordPress for two years so I am familiar with the program. The Website https://www.ayokasystems.com.

I added a page and it is not showing in the menu bar. The page does work.

Above is the link to the page I am trying to make show up on the menu bar.
