Bottom bar not spaning the entire window

[exilera]

Please check the attached .gif. The bottom bar is not spanning the entire window. Would anyone happen to know how to correct this?

Edit:

Would this code be the culprit, in the 'memberlist' template?

<td class="tfoot" colspan="$totalcols" align="$stylevar[right]">
		<span class="smallfont">
		<if condition="$show['usergroup']">
			<input type="submit" class="button" value="$vbphrase[remove_selected_users]" />
		<else />
			<phrase 1="$first" 2="$last" 3="$totalusers">$vbphrase[showing_results_x_to_y_of_z]</phrase>
