Any idea why this happen?

       public ActionResult ImageProven(ItemModel model)
       {
           string id = model.Form_Id.ToString();
 
           if (model != null)
           {
               var addImage = db.tbl_detailItem.Where(z => z.item_id == model.item_id).FirstOrDefault();
               if (model.file1 != null)
               {
                   var allowedExtensions = new[] { ".Jpg", ".png", ".jpg", "jpeg", ".pptx" };
 
                   var fileName = Path.GetFileName(model.file1.FileName); //getting only file name
                   var ext = Path.GetExtension(model.file1.FileName); //getting the extension(ex-.jpg)
                   if (allowedExtensions.Contains(ext)) //check what type of extension
                   {
                       string name = Path.GetFileNameWithoutExtension(fileName); //getting file name without extension
                       string myfile = name + ext;
                       // store the file inside ~/project folder(Img)
                       var path = Path.Combine(Server.MapPath("~/ImageStore/form/"), myfile);
                       model.file1.SaveAs(path);
                       addImage.auditeeAttach = "~/ImageStore/form/" + myfile;
                       if (String.IsNullOrEmpty(addImage.auditeeAttach))
                       {
                           addImage.auditeeAttach = "~/ImageStore/form/";
                       }
                   }
                   else
                   {
                       ViewBag.message = "Please choose only Image file or Email File";
                       return View();
                   }
               }
 
               db.SaveChanges();
           }
           return RedirectToAction("AuditeeListItemDetail", "Auditee", new { id });
       }
