editor is generating a header attribute within a csv marshal tag which causes errors

Create a JBoss Fuse project with blueprint template. Delete existing route from the blueprint.xml using Source tab. Paste following route in Source tab. <route id= "extract-route" > <from id= "cron" uri= "{{extract.schedule}}" /> <transacted id= "_transacted" ref= "PROPAGATION_REQUIRED" /> <log id= "log_start" message= "Firing db call" /> <to id= "to_select" uri= "sql:classpath:cx_extract_combined.sql" /> <to id= "to_update" uri= "sql:{{sql.cx.update}}" /> <marshal id= "marshal" > <csv delimiter= "|" > <header>person_id</header> <header>first_name</header> <header>last_name</header> <header>email_address</header> <header>collar_number</header> <header>user_id</header> <header>ex_employee</header> <header>post_rank</header> <header>job_title</header> </csv> </marshal> <to id= "to_local_file" uri= "{{local.generated.file.path}}?fileName=cx_export.csv.${date:now:yyyy-MM-dd-HHmmss}&amp;tempPrefix=." /> </route> Now switch to Design tab and than back to Source tab. We see extra option header added to <csv .../> tag. Check screen-shot step_3.png file. <marshal id= "marshal" > <csv delimiter= "|" header= "[person_id, first_name, last_name, email_address, collar_number, user_id, ex_employee, post_rank, job_title]" > <header>person_id</header> <header>first_name</header> <header>last_name</header> <header>email_address</header> <header>collar_number</header> <header>user_id</header> <header>ex_employee</header> <header>post_rank</header> <header>job_title</header> </csv> </marshal> Also Source tab point it as a invalid statement. Screenshot attached.
