Shortcode is not working

Hi Michael
I think i´ve probably did something wrong i tried to create a shortcode – so that in list just date, time, title and location are appearing – no link at all.
I´ve inserted following short code – but it´s not working – may you can help.
[event-list num_events=4 show_filterbar=false show_details=false link_to_event=false]

Thank you and best regards
