Hi Phil,
Syncfusion Greetings!
We have checked the provided document and document contains Small caps content. Currently, Document editor doesn’t have support for Small caps, so only all content rendered in lower case. We have support for All Caps property , if you change it and it will properly.
Please find modified document: https://www.syncfusion.com/downloads/support/directtrac/general/ze/MM-Letterhead-Boston-641689753
Please let us know if you have any questions.
Regards,
Suriya M.
