Have a look at these VBO issues:


views_bulk_operations_action_load_list not working.

Since you're using the 7.x-3.3 release of VBO, I recommend you retry your scenario with at least the 7.x-3.4 release. However, as per this comment you might only get it to work using the latest DEV version of VBO.
