Yeah that's right. I've had the same Xfader on my Vestax PMC05mk2 since I got it (about a year ago!), it bleeds heaps but I haven't gotten around to replacing it yet.
One way I've been able to stop the bleeding is to get one of those metal twist ties that are covered in plastic (they come with bread or garbage bags. If you stick it in the fader on the side, and then bend it down so that it's not sticking directly up, it stops the fader from reaching all the way across.
You'll find with a fader that bleeds that if you move the fader a millimeter away from the end, it stops. That's what this is for - stopping it reaching the very end. It's not as good as replacing your fader but if you couldn't be bothered it's a very cheap alternative, or a temp fix.
