Make sure you are keeping what very little pressure there is focused on the spine of the razor, you want the strop to deflect at the spine, not the edge, this will fold it over.
Hold the strop tight, very light pressure and concentrate on not lifting that spine for any reason. You'll hear an audible difference in pitch if you lift the spine, it will sound thin and high pitched. Also you may have put too much pressure on the toe end of the razor, keep the blade flat and even across the strop. In a couple weeks you'll be stropping so fast you'll hardly believe you ever made this post.
The scratches probably didn't hurt your strop, rub some leather conditioner into it and then press it with the smooth side of a coffee mug to smooth it out.
