Titles don't disappear in Event Manager Theme

Hi
I installed the plugin on a Event Manager Theme installation to remove the titles on all inner pages. (website is http://www.smart-change-management-camp.com) Unfortunately, neither the general options in the Theme settings, or individual “hide title” on the schedule and speaker page hide the title.

Thanks for an idea how to solve this issue.
