Thanks for using our products.
I have tested the scenario using Aspose.Pdf for .NET 5.3.0 and I am unable to notice any problem. Please take a look over attached resultant PDF document that I have generated using XML file which you have shared in your earlier post. In the problem still persists, please share further details. We are really sorry for this inconvenience.
