Edit Customizr slider

Hello All,

I’m pretty new to WordPress and keep finding out new things, but there is one subject that eludes me.

I can’t seem to find out how to customize the slider on the first page of the Customizr theme.
I’ve made a new slider and that works perfectly fine exactly as I want it to, but can’t find out where/how I can change the slider on the first page.

Sorry for the noobish question, but I was unable to find a similar question anywhere (on google ofcourse).

Thanks.
