Remove bar from hamburguer menu HELP

Site URL: https://www.joannestonedesign.com/

Hi, I need some help.

I added a hamburger menu in my desktop version. I wanted to know if there is a possibility of removing that white / gray bar that appears in the menu.

Also I changed the default cart of squarapace for the word CART but it does not appear in the mobile version. Does anyone know how I can solve that?

pls help.

thank you very much,

/* desktop bar */
@media screen and (min-width:992px) {
.header-menu-nav-folder[data-folder="root"] {
    overflow: hidden;
}
}

Q2. Which cart? Can you take a screenshot?
