Beaver Builder Content Slider

Hi Tom,

I am working on a new site and have installed GP Premium (with the generic child theme) together with Beaver Builder. The URL of the new site is http://schluchter.testumgebung.at

On the homepage I have used the Beaver Builder "Content Slider"-Module. Everything works perfect, except that the navigation arrows are not visible on top of the slide-pictures. When I switch to another theme (Twenty Seventeen) everything works as expected.

I have figured out that there might be a problem with this class: .fl-post-slider-navigation svg

Could you have a look into that? Thank you very much and Best Regards from Austria, Christoph
