C# MVC .rdlc Report perfect 1 report but multiple displays on itself

Hello everyone,

I have a C# MVC application when I generate 1 report from a record it loads and works perfectly. When I generate 2 or more reports that is supposed to open in the same PDF window they end up displaying on top of each other. I’m not exactly sure why this is happening I have the page set 8.5 by 11 and correct side and ConsumeContainerWhitespace = true. In the report my margin is ,,, so all 0. Maybe one of you will see something that should be changed. Here is my code.

case "Generate All":
                    LocalReport localReport = new LocalReport()
                    {
                        ReportPath = Server.MapPath("~/ReportForms/VirtualService3.rdlc")
                    };                                                            
                    ReportDataSource rds = new ReportDataSource("Service_Fields", model.ListQuotes); 
                    localReport.DataSources.Add(rds);

                    string reportType = "PDF";
                    string mimeType, encoding, fileNameExtension;

                    string deviceInfo =
                        "<DeviceInfo>" +"   <OutputFormat>"+reportType+"</OutputFormat>" +"   <PageWidth>8.5in</PageWidth>" +"   <PageHeight>11in</PageHeight>" +"   <MarginTop>0.5in</MarginTop>" +"   <MarginLeft>0in</MarginLeft>" +"   <MarginRight>0in</MarginRight>" +"   <MarginBottom>0in</MarginBottom>" +"</DeviceInfo>";

                    Warning[] warnings;
                    string[] streams;
                    byte[] renderedBytes;
                    //localReport.GetParameters();

                    renderedBytes = localReport.Render(
                        reportType,
                        deviceInfo,
                        out mimeType,
                        out encoding,
                        out fileNameExtension,
                        out streams,
                        out warnings);                   

                    return File(renderedBytes, mimeType);
            }

            //model.List = getter.GetRows(query);
            //testGenerator(model.List);
            //model.Settings = GetTableSettings();

            return View("VirtualService", model);
