It was to do with a top of bank linetype that we use, and i was wanting to show the linetype on the correct side. I fixed it by creating a new linetype and feature line style.
If you can't reverse it, how about exploding it to a polyline, then you can reverse it. Or creating a linetype for the opposite direction.
