Undefined property: stdClass::$cvm in contextual_view_modes_nodes_node_update()

I am seeing the following notice quite intermittently. The module seems to be working ok otherwise

Notice: Undefined property: stdClass::$cvm in contextual_view_modes_nodes_node_update() (line 151 of /home/parallax2.drupal7.com/public_html/www/sites/all/modules/contextual_view_modes/modules/contextual_view_modes_nodes/contextual_view_modes_nodes.module).
