Bad mobile view

I have found mistake in mobile view of Events Manager (5.6.6.1). If I click in WP (4.6.1) to Events – reservations – roll down to “Events with allowed reservations”, there is preselected “Future events”, you cannot change it to “passed events” when you are using mobile phone view 🙁 I think this is mistake.

I think it is problem in EM plugin 🙁
