Using publisher theme on site, changed the scheme to black and white and gradient effect still shows

I’ve been using the Publisher theme and have done everything to change the bottom of my site to white. Even when I change the accent in schemes, this gradient effect still appears. Any way to change it to white? I don’t have a footer added either; it’s something that definitely needs to be added to the code, but I have no idea. Please help, thanks!

The issue is most likely be related to assigning the color scheme to this current section or maybe it might be hard coded in your css file. Please share your store’s link
