Error when updating MS Project file

I'm facing a problem when updating a MPP file.

All Tasks are being set as collapsible (like sumary tasks), even if a task don't have children, and the ExtendedAttributes are being set to 'dropdown column' and fixed values (see attached image).

That's a sequence to simulate the problem:

1- Create a empty file.
2- Create some tasks with Aspose.Tasks.
3- Open file with MS Project, change some data and save file.
4- Open the file with Aspose.Tasks and save .

The attached source can simulate this.

Thank you for attention.
