We're looking at using the RadRichTextBox in our application. For testing, I have a very simple docx with 2 mergefields
1. One mergefield in the header of the docx
2. One mergefield in the body of the docx.
When loading the .docx using your sample(SaveAndSaveAs_WFP) , the mergefield in the body appears but the mergfield in the header does not.
How can this be resolved? Is this a settings issue?
