Page jumping to the right

Hi. I have customized a wordpress site. All works fine, but the “Contact” page jumps to the right. I’ve deleted it and created a new page. Still the problem remains. Now I’m also getting a “-3” on the link, which I can’t edit.

If you go to the link and click on other pages in the menu bar, you’ll see how the Contact page shifts. Let me know if you have any ideas how to fix.

Thank you,
Mark
