I need to add 2 sections on my web page. Like below

Team Member: Brands:

And I used to the new template to add those new items.

But finally all the new items I added, show in both places.

My Controller

public ActionResult RenderAboutTeamMember()
    {List<MemberPreview> model = new List<MemberPreview>();
        IPublishedContent memberPage = CurrentPage.AncestorOrSelf(1).DescendantsOrSelf().Where(x => x.DocumentTypeAlias == "about").FirstOrDefault();


        foreach (IPublishedContent page in memberPage.Children)
        {
            int imageId2 = page.GetPropertyValue<int>("MemberImage");
            var mediaItem2 = Umbraco.Media(imageId2);
            model.Add(new MemberPreview(page.Name, 
            page.GetPropertyValue<string>("memberIntro"), 
            page.GetPropertyValue<string>("memberPost"), 
            page.GetPropertyValue<string>("linkedinLink"), 
            page.GetPropertyValue<string>("twitterLink"), 
            page.GetPropertyValue<string>("facebookLink"), 
            page.GetPropertyValue<string>("instaLink"),mediaItem2.Url,page.Url));

        }

        return PartialView("~/Views/Partials/Home/About/About_TeamMembers.cshtml", model);
    }



    public ActionResult RenderAboutBrands()
    {
        List<Brands> model = new List<Brands>();
        IPublishedContent homePage = 
        CurrentPage.AncestorOrSelf(1).DescendantsOrSelf().Where(x => 
         x.DocumentTypeAlias == "about").FirstOrDefault();
        ArchetypeModel Brands = 
        homePage.GetPropertyValue<ArchetypeModel>("brands");

        foreach (ArchetypeFieldsetModel fieldset in Brands)
        {
          var mediaItem = fieldset.GetValue<IPublishedContent>("imageLogo");
          string Bimage = mediaItem.Url;
          model.Add(new Brands(fieldset.GetValue<string>("brandName"), Bimage));

        }
        return PartialView("~/Views/Partials/Home/About/About_Brands.cshtml", model);
    }

My Brand Model:

 public class BrandPreview
{
    public string BrandName { get; set; }
    public string BrandImageUrl { get; set; }
    public string BrandLink { get; set; }
    public string BrandLinkUrl { get; set; }

    public BrandPreview(string brandname, string brandimageurl, string brandlinkurl,string brandlink)
    {
        BrandName = brandname;
        BrandImageUrl = brandimageurl;
        BrandLink = brandlink;
        BrandLinkUrl = brandlinkurl;
    }
}

My Member Model:

 public class MemberPreview
{
    public string MemberName { get; set; }
    public string MemberPost { get; set; }
    public string MemberIntroduction { get; set; }
    public string MemberImageUrl { get; set; }
    public string MemberLinkUrl { get; set; }

    public string MemberLinkedin { get; set; }
    public string MemberTwitter { get; set; }
    public string MemberFacebook { get; set; }
    public string MemberInstagram { get; set; }

    public MemberPreview(string membername,string memberpost, string memberintro, string memberlinkedinLink, string membertwitterLink, string memberfaceBookLink, string memberinstragramLink, string memberimageurl, string memberlinkurl)
    {
        MemberName = membername;
        MemberPost = memberpost;
        MemberIntroduction = memberintro;
        MemberImageUrl = memberimageurl;
        MemberLinkUrl = memberlinkurl;

        MemberLinkedin = memberlinkedinLink;
        MemberTwitter = membertwitterLink;
        MemberFacebook = memberfaceBookLink;
        MemberInstagram = memberinstragramLink;
    }
}

I think problem is controller page code.in hear identify all the children page in current page. How can fix it???
