Thanks for your request. I managed to reproduce the problem on my side. The problem occurs because your document contains OOXML objects. Unfortunately, currently, Aspose.Words does not support OOXML Diagrams and Charts. Your request has been linked to the appropriate issue. We will let you know once this feature is supported. Most likely it will be somewhere in the end of August.
