Thanks for your request. The problem with chart occurs because Aspose.Words does not support rendering DrawingML diagrams and charts. Your request has been linked to the appropriate issue. You will be notified as soon as it is resolved.
The problem on page 8 of your PDF occurs because there is a floating table. Unfortunately, currently Aspose.Words does not support positioning of floating tables upon rendering. That is why content is misplaced. Your request has been linked to the appropriate issue. WE will let you know once it is resolved. As a temporary solution of this issue, You can try avoid using floating tables and use inline tables instead.
Best regards,
