29319493 - Distinguish between Comments & Private Comment Column Types

Previously, in the AERS signal configuration, the Drug-Event Columns table referenced column type Note for both Comments and Private Comments and column type Note Date for both Comment Dates and Private Comment Dates.

This issue has been fixed. The Product-Event Columns table now uses column types Note, Note Date, Private Note, and Private Note Date for the columns Comment, Comment Date, Private Comment, and Private Comment Date, respectively.
