Problem with group filter

Hi,
we are facing an issue with the plugin filter function.
The plugin it’s actually awesome and does everything that we need, but it seems we can’t get the filter to work.
Everything seems fine, but groups “buttons” to filter are not clickable.
Do you think it’s a problem with the theme maybe?
