  1. Incorrect data after saving mpp file

if i try to run this code is successful

        var project = new Project("template.mpp");
        //logic to add extented attributes in project
        SetAllExtendedAttribute(ref project, listGuidProject);

        fullInfo.TasksProject = fullInfo.TasksProject.OrderBy(a => a.WBS).ToList();
        //logic to add task in project
        SetAllTask(ref project, fullInfo.TasksProject);

        var memoryStream = new MemoryStream();

        project.Save(memoryStream, new MPPSaveOptions() { WriteViewData = true });

        memoryStream.Position = 0;
        return new InfoExportMppDto
            File = memoryStream

but output date in file incorrect

“Стадия ЖЦ” - its extented attributes Text22
“Вид работ” - its extended attibutes Text26

Default field write correct, but extended attributes no. They should contain words, but symbols or single letters are displayed that are not related to the data. And if you import this file and upload it to stream and then to the project , then the data inside is correct
