Hello Sebastian,
I believe Matthias is correct. The suggested workaround for this is to use a a table without borders. The table should have two cells, side-by-side. In the first cell insert the <%{Section}%> field, and in the second cell, insert <%{Text}%>.
The reason this is occuring is because, as Matthias stated, your <%{Text}%> field starts with a newline. This is the case with all Integrity rich text fields.
This is covered by CS91937: Issues with Word/Gateway: Carriage Returns/Line Feeds inserted between non-RTF and rich text content, and would attach you to defect RFC 369604. Please contactPTC Integrity Supportto have your organization associated with this enhancement request
Regards,
Kael
