Did you make change directly to theme file ? If so, please move it over to child theme. It's not healthy to keep modifying upon directly edited original theme file.

Meanwhile, put this in theme's Custom CSS option.
.hgroup-right { margin-top: 12px; }
.hgroup-wrap { padding-bottom: 12px; }
Also, there seems to be error in plugin (or anything that outputs CSS to html head) because there is a whole CSS file containing this, for example, which is wrong syntax.
HTML BODY DIV.wrapper HEADER IMG.header-image {
font-size: 55px !important;
}
