is it normal for when I run Embedded export to pdf it resets embedded report

I am setting up an apps own data embedded export to pdf using ExportToFileInGroup and then polling to see if the file is available and of course download the file. 

However, I noticed when stepping through the code when I run the above steps (it doesn't appear to be consistent but always happens between the above 2) my embedded report resets.  What I mean by that is I navigate to the embedded report, select the one I want, hit Export to PDF and then the report goes away to default from when i arrive at our site.  Sometimes it exports and sometimes it doesn't.  

I can't seem to find any error messages when it does this.  I've turned on try and catch but no error messages.  

     var powerBIReportExportConfiguration = new PowerBIReportExportConfiguration
     {

         Identities = new List<EffectiveIdentity>
         {
             new EffectiveIdentity
             {
                 Username = userName.ToString(),
                 Roles =new List<string> { "RLS" },
                 Datasets = new List<string> { DATSETID }
             }
 },
         Settings = new ExportReportSettings
         {
             Locale = "en-us"
           
         },
 


     };

     var exportRequest = new ExportReportRequest
     {
         Format = format,
         PowerBIReportConfiguration = powerBIReportExportConfiguration
     };
     if (ExportFilter != "")
     {
         exportRequest.PowerBIReportConfiguration.ReportLevelFilters =
           new List<ExportFilter>() {
     new ExportFilter { Filter = ExportFilter }
           };
     }
     

     try
     {
      
         var export =  client.Reports.ExportToFileInGroup(groupId, reportId, exportRequest);

         string exportId = export.Id.ToString();
