Thank you for using Syncfusion products.
When analyzed the behavior which you have mentioned in the previous update, we are not able to reproduce the issue, we tried importing two different document with pages in rotation angle of 90 degree and 180 degree to an new document. The created document found to restore the pages in same angles.
