Menu with links containing anchors does not work?

I am using the Fixer theme with Upfront.

When I create a Menu, and add the links, I have found that using a link with an anchor, like the example below, does not work properly if the hyperlink is on a different page than the page with the link:

this doesn't work either:

You can see this odd behavior on the page below, in the top navigation:

Notice how the links to "About", "Get a Quote" and "Contact" which have anchors, do not work at all. When clicked - nothing happens... no page refresh, or anything, the click seems to be ignored. However the same links will work on the home page, but not on any other pages.

Does anyone have any suggestions or a remedy for this?

Thank you for your support.
