Hello,
I saw the screenshots you attached.
To remove the back button from the shop page categories you need to add the following Custom CSS in the Custom CSS for Desktop area under Theme Settings >> Custom CSS.
.page-title.with-back-btn .woodmart-back-btn {
display: none;
}
There is no option in theme settings to display the categories on desktop and hide for mobile. So you need to add the following Custom CSS in the Custom CSS for Mobile area under Theme Settings >> Custom CSS.
.nav-shop .woodmart-show-categories {
display: none;
}
Best Regards.
