Filterbar showing

Hi
I´ve created the following shortcode – this was working fine for past months… but suddenly filterbar is showing?
[event-list num_events=4 show_filterbar=”false” show_details=”false” link_to_event=”false”]

After i´ve seen i´ve made the update of the plugin but still the filterbar is showing.
Can you please help me?
