Nonprofit WP Theme Buttons

Hi Experts,

If you go to www.iwscc.ca you will see in the header 2 orange buttons: Corporate and Self-Registration, both going to #

Under WP Admin, I see that this theme is called Nonprofit, and the buttons are set in Theme Options >Address Bar, and ou will see in the snapshot that I can set the buttons label, but not the url. My questions are...

1- How do I remove the Corporate button? If I leave it blank, I just get an orange square.

2- How can I actually set an url to these?

I know I can create a child theme, and address #1 with CSS and #2 with JS, but I think there should be an easier way since the theme provides these buttons.

BTW- even though in the screenshot it says Webdivia, under themes it says Nonprofit. I just inherited this website.

Thank you,
