Okay, I found that in your template "forumdisplay.css" for that style, there wsa the following CSS class selector:

.forumbits ol {
	float: {vb:stylevar left};
	width: 50%;
	clear:both;
}

I edited it to read:

.forumbits ol {
	float: {vb:stylevar left};
	width: 100%;
	clear:both;
}

That seems to have fixed the issue.
