Buttons do not show on mobile phone with iOS or Android. Tablets and laptops ok.

So I’ve been editing and customizing one of the site library themes. I’ve pretty much tailored it to my needs but I have one thing I havn’t been able to solve.

On computers and tablets that are not considered a mobile device (iPad for example) the page renders as expected. However on mobile phones, both iPhones and Android I have two buttons that just don’t show and I can’t figure out why or how to fix it.

You can see the buttons labeled “Sign Up For A Class” in the menu and below the list items on the left side of the screen on tablets and computers. On mobile devices the button below the list items should be directly below the “Course Options” list. (I’m not really concerned with the button in the header as long as this button is visible to mobile devices.
