Customizing colors – unable to see color menu

Hi,

I’m very new to WordPress and am setting up a blog but haven’t launched it yet. Have been playing around with themes, and finally decided on aReview, but when I go into WordPress to customize colors, I can no longer see the many color tabs that were there before (and the one that does display is out of alignment).

Tried installing a new theme with the same result.

Here is a screenshot of what the menu looks like for me – https://postimg.org/image/d2y07j1ir/

Thanks your advice on how to resolve this.
