Undoing some effects of a purchased Childtheme

I am wondering if there is a way to turn off some of the functions in the arcade child theme I bought.

I like the search bar/shopping cart appearance on the plain “storefront” theme more.

On the standard Storefront, the search bar/cart looks like this: https://cloudup.com/clADn4BNoAE

On the arcade childtheme, if you just look at my site: style-booklet.com, it doesn’t look like that.

Is there a way to revert it to the standard childtheme.

Thanks!
