I don't check the Include comments for database objects option, but generated SQL includes comments.
Generated SQL script can contains two types of comments:
# comments for a human that reads the script. Line starts with '--'
# comments on database object. DDL command e.g.
This options turns on/off the latter comments.
Hope it helps.
I meant comment like that
nimetus varchar(60) NOT NULL COMMENT 'Ametikoha nimetus.',
