Error message in dashboard – Warning: Missing argument 2

The following error message appears repeatedly on the dashboard of my site:
Warning: Missing argument 2 for Ai1ec_View_Helper::the_title_admin() in /home/content/16/10701316/html/wp-content/plugins/all-in-one-event-calendar/app/helper/class-ai1ec-view-helper.php on line 652

Here is a link to the site: http://mikelawsonbooks.com/

This is also occurring on another site I manage: http://authenticpath.net/

Can this be fixed somehow? The plugin functions, but it looks bad in the dashboard when clients update on their own.

Both sites are studiopress themes.
