Error WPML and theme after switching to another language

Hello,

Please take a look at http://test.paulleegwater.com/
At first (dutch language) everything works fine.

For example when I navigate to:
http://test.paulleegwater.com/assortiment/

and I hit the flag for example Germany I get an error:
Warning: end() [function.end]: Passed variable is not an array or object in /home/paulleegwa/domains/test.paulleegwater.com/public_html/wp-content/themes/enfold/template-builder.php on line 33

Can you please take a look.
