I have created Document Definition using the .fsp file extension and create the project.
Project > Document Definations > New > Semi Structured document and select Document PDF and .fsp file.
Once the file is loaded successfully, I will change the definition section likes text box margin, checkbox area, top margin, left margin and save the document and publish.
When I go to Verification Station, the Document Section appear correctly as per what I set.
But when I go to Web Verification, the Document Section is not correct.
