[otrs] Problem with email subject

Hi When I create a new Email-Ticket in OTRS by clicking on the Email-Ticket icon on the menu, there is an extra "Re:" in the subject line, like this: Re: [Ticket#2005121310000194] Subject here This is a new email, and not a reply email, so I don't want the "Re:". Why is it there, and how can this be removed? Torgeir
