VC Image Carousel not responsive

Hello,

I’m using the LeadInjection theme from Themeforest and I’m having a problem with the default VC Image Carousel. It works fine on large screens but is not responsive.

The theme came with it’s own slider, but the plugin was massive and slowing down the site speed immensely so I got rid of it. Is there something that can be done to make the VC carousel responsive? It seems like, from the research I’ve done online, it should work fine.

Thanks,
Peter
