How to display new/updated form overlay in AE
The problem is, the form overlay is missing from the XML file in the _Forms folder in the render server cache folder.
To display the new content when printing, emailing, or exporting, you must clear the Render Server cache folder.
Stop the Render Server service, delete the content of the render server cache folder, and then restart the Render Server service.
Render Server will recreate the XML file when the document is exported.
