Shortcode showing as text on iphone

Hi –

Thermometer works fine on laptop browser, but when I visit the site on my iphone I don’t get the thermometer, just the actual shortcode text (e.g. [wpch_thermometer id=”30″]).

I’m using the Parabola theme for this, and the shortcode has been added to the Extra Text field on the Presentation Page.
