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.
