I need to build one envelope with three composites:

1. a plain PDF with no signers,

2. a server template with roles mapped to recipients,

3. a flat PDF that overrides a server template’s original doc and maps template roles RoleA → Employee (routing 1) and RoleB → Owner (routing 2).

Problem
In composite #3, the tabs/fields from the server template appear on the wrong document (seem to land on the first doc), and the template for the flat PDF looks “ignored.

What am I missing or doing wrong that it showing 3 documents as required but adding only last assigned template’s tab and text to complete envelope [i.e. overlaying on first document only ] and ignoring 2nd server template tabs and fields and not adding 3rd template it’s respective 3rd document ???
