Div element is not rendering in asp.net core mvc

Question

I am working on a project. I am using a view from that i am calling partial view. I have a razor code in partial view which displays cards. I have tested using breakpoint. everything is working well but the div is not rendering. I even checked using inspect element in chrome and not div code is rendered in it. Please suggest any solution.

 

Main View from which partial view is called

@model Tuple<Booking,Customer >
@{
ViewData["Title"] = "SingleView";
Layout = "~/Views/Shared/_NiyaSpaLayout.cshtml";
}
@{
var sname = ViewBag.serviceName;
}
<div class="w3_breadcrumb">
<div class="breadcrumb-inner">
<ul>
<li><a href="">Our Services</a> <i> /</i></li>
<li>@sname</li>
</ul>
</div>
</div>
<div class="w3_content_agilleinfo_inner">
<div class="container">
@{
switch (sname)
{
case "Facials": await Html.PartialAsync("_Facials",Model);
break;
case "Waxing": await Html.PartialAsync("_Waxing");
break;
case "Massage": await Html.PartialAsync("_Massage");
break;
case "Haircut": await Html.PartialAsync("_Haircut");
break;
default:
break;
}
}
</div>
</div>

Partial View

@using NiyaSpa.Models
@model Tuple<Booking, Customer>
<div class="inner-agile-w3l-part-head">
<h2 class="w3l-inner-h-title">Facials</h2>
</div>
