How do I remove a trailer from my profile page?

Hi there,

Hope someone is able to help. Rather than showing my demo reel, for whatever reason a trailer for one of my films shows at the top of my page. This only happened recently, since the release of the film in question. There appears to be no option to remove it, or change it from being the primary / default video shown. I have no issue with it being included as one of my videos, only that it takes precedence over my demo reel. Is there any way of either changing its primary / default status or failing that, removing it?

Thanks!
