HTML bug in the shortcodes in CoursePress Pro

There is a bug in the HTML code in \includes\classes\class.shortcodes.php on line 4161 in the latest version
This is causing big layout problems in some wordpress themes.
This code:
<div class="clearfix" style="clear: both;" />
has to be like this:
<div class="clearfix" style="clear: both;"></div>
Please fix when you can.
