Hello,
Oh, I see.
Add the below code to Theme Options > Custom CSS
.page-heading nav > a:first-of-type, .page-heading #breadcrumb > a:first-of-type {font-size: 0 !important;}
.page-heading nav > a:first-of-type:before, .page-heading #breadcrumb > a:first-of-type:before {
font-family:'xstore-icons';
content: '\e953';
font-size: 14px;
}
Regards
