Approval FYI shows draft attachment

Summary:

We're using BI reports to feed letter content - when we create a document record of the type "Resignation" for example, the BI report path on that letter merges information from doc record DFF context and also from the person and assignment data.

Our issue however, is that the OOTB for this splashes "DRAFT" across it so that when the approval transaction goes to the FYI receivers (manager and employee in this case), all they see is the content that comes from the assignment merged into the letter, but not any post-submit logic content and no Document Record DFF content, and a big 'DRAFT' name across it.
