Number appearing after I echo footer sidebar

Hi,

I am echoing 2 footer sidebars, but for reaso I am getting a “1” displaying under each column.

Does anyone know why this is?

This is my code:

	<div class="container">
		<div class="vc_col-md-12">
			<div class="vc_col-md-6">
				<?php echo dynamic_sidebar('footer-sidebar-1');?>
			</div>	
			<div class="vc_col-md-6">
				<?php echo dynamic_sidebar('footer-sidebar-2');?>
			</div>	
		</div>
	</div>

Thanks
