Side Bar - One page name is the wrong colour [RESOLVED]

Once the burger appears in the responsive version for mobile phones, one of the page names appears in white as opposed to dark grey like all the other page names on the side bar. I don’t know why this is happening and why only one page description appears in white.

How I can resolve this?

I managed to resolve it. Even through the right colour was specified it was still wrong. Just selected the nav bar items clicked on an alternative colour and then clicked back on the original colour that I wanted and it worked.
