Thats a dead link, as far as top1-top7 they seem to be working fine try making custom modules and removing the modules you have right now. I used the code for top1 - top7 last night to make some custom module positions and there is now way a issue like that could be because of the coding. 
the width to those modules are set dynamically.
	<?php if( $this->countModules('top1') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top1']['class']; ?>" style="width: <?php echo $topsl1['top1']['width']; ?>;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top1" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
	<?php if( $this->countModules('top2') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top2']['class']; ?>" style="width: <?php echo $topsl1['top2']['width']; ?>;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top2" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
	<?php if( $this->countModules('top3') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top3']['class']; ?>" style="width: <?php echo $topsl1['top3']['width']; ?>;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top3" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
you can set your own widths if you have to:
	<?php if( $this->countModules('top1') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top1']['class']; ?>" style="width: 214px;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top1" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
	<?php if( $this->countModules('top2') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top2']['class']; ?>" style="width: 535px;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top2" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
	<?php if( $this->countModules('top3') ): ?>
	<div class="gk-box column gk-box<?php echo $topsl1['top3']['class']; ?>" style="width: 359px;;">
		<div class="gk-box-wrap">
			<jdoc:include type="modules" name="top3" style="gavickpro" />
		</div>
	</div>
	<?php endif; ?>
