ANCHOR URLS NOT WORKING IN MENU

I have a global menu items that need to need to link to respective sections/anchors on the home page, regardless of what page the visitor is currently on. I am using the URL option for the menu items and pointing to a url formatted as http://example.com/#about. I have tried making the actual anchor using the anchor option on a text item as well as using the code element. Nothing happens when the menu item is clicked. However, right clicking and opening in new tab brings up the correct page/section. I have also tried linking non-menu text to the anchor but have the same problem. The problem is very similar to the one discussed here: https://premium.wpmudev.org/forums/topic/two-separate-menus-for-homepage-and-blog-yet-links-on-blog-do-not-work-for-about-and-contact

I have deactivated plugins and problem still exists.
Thanks,
