When I click on a submenu link it disappears

I want to change the name of one of my sub menu links when I click on services and then try to change residential to Home the button just pops away and doesnt allow me to fix it. Any Suggestions?

Hi

The best practice in this case is to build the “Services” menu from scratch.
