H2 header in WPRM not working because of Ashe Pro CSS

I asked Brecht at WP Recipe Maker for support, and he replied with the following:

<span style=”color: #000000; font-family: sans-serif; font-size: 13px;”>Your theme seems to be messing with things. I can see some CSS code that’s forcing the size of print button:</span>

.wprm-recipe-print, .<wbr />wprm-jump-to-recipe-shortcode,<wbr /> .wprm-print-recipe-shortcode {
        font-size: 13px;
        line-height: 1;
        padding:10px 15px !important
    }

<span style=”color: #000000; font-family: sans-serif; font-size: 13px;”>Could you check with your theme support where/how that can be removed? They should not be doing that.</span>

I searched for this in the CSS and could not find it.
