Hello,

Try to add the following code snippet to the Custom CSS area in Theme Settings.

body .single-breadcrumbs-wrapper .woocommerce-breadcrumb .breadcrumb-last {
	display: block;
}

body .single-breadcrumbs-wrapper .woocommerce-breadcrumb .breadcrumb-link-last {
	margin-right: 6px;
}

body .single-breadcrumbs-wrapper .woocommerce-breadcrumb .breadcrumb-link-last:after {
	content: "/"
}

body .single-breadcrumbs-wrapper .woocommerce-breadcrumb .breadcrumb-link-last {
	color: #8e8e8e;
	font-weight: 400;
}

Regards
