Events Filtering Stopped New Theme

Hi,
I wondered if anyone can help? I’ve been using Events Manager for a while and it’s worked perfectly. However, I recently installed the ‘Fundify’ theme and the event filtering in the admin section has stopped working.
The problem only happens with this theme; we’ve tried 5 other themes and there’s no problem so we can only infer it’s the theme. I have found a thread where the EM author mentions themes breaking the plugin.
Has anyone had experience of this and could you guide me in the right direction?
Many thanks
