Clearing View Engine in MVC breaks sitemap breadcrumb styles

Question

In a web application MVC 5 that I develop to improve the effectiveness of the mechanisms I clear view and add only RazorViewEnginein the Global.asax.csvia ViewEngines.Engines.Clear();, and it breaks down the styles palettes mcc sitemap

Before

After

My partial sitemap view (SiteMapPathHelperModel.cshtml) looks like

@model MvcSiteMapProvider.Web.Html.Models.SiteMapPathHelperModel
@using System.Web.Mvc.Html
@using System.Linq
@using MvcSiteMapProvider.Web.Html.Models
<ol class="breadcrumb">
    @foreach (var node in Model)
    {
        if (node == Model.Last())
        {
            <li class="active">
                <strong>@Html.DisplayFor(m => node)</strong>
            </li>
        }
        else
        {
            <li>
                @if (node.Title == "Home")
                {
                    <a href="/"><i class="fa fa-lg fa-home"></i></a>

                }
                else
                {
                    @Html.DisplayFor(m => node)
                }
            </li>
        }
    }
</ol>

It seems somehow that it is returning to a different implementation than partial under views> shared> display templates

What could be the reason?

Edit

I missed the important information here, another developer did it at the bottom of Application_Start ()

ViewEngines.Engines.Add(new RazorViewEngine
{
     PartialViewLocationFormats = new string[]
     {
           "~/Areas/Shared/{0}.cshtml",
     }
});

            {
                PartialViewLocationFormats = new string[]
                {
                    "~/Areas/Shared/{0}.cshtml",
                    "~/Views/{1}/{0}.cshtml"
                    "~/Views/Shared/{0}.cshtml",
                }

        ViewEngines.Engines.Add(new RazorViewEngine());

        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
