Can't reproduce your issue. I see all icons very well, so either you use some kind of ad-blocking solution, or your network restricts the loading of those images (they are loaded from an online source).
You added Music, Browser and Themes to the list of 'for which apps should favorites be shown', but you haven't added any actual favorites.
Example: Browser - Load a website -> Menu button -> "Share" button on bottom-right -> "Add to favorites".
