Theme issue

I realize it’s a bit of an older theme…not sure if it’s still being supported/updated etc, so I’m open to any similar alternatives suggested as well but..

I have a new catering site up https://www.edithscatering.com/ with the Restaurateur theme and I can bring up the customized settings area for the slider but all it gives me is an option to set how many seconds each image displays for…I can’t for the life of me see any area to actually add images to create the slider itself?

Thanks
