Although this may not be fixed as of VW9.0.1, it was a characteristic of VW8.5.2. The different layers, I'm assuming, are at different scales. If you have a 1:1 whose origin is offset from the CENTRE OF THE PAGE OUTLINE by a certain distance, a layer whose scale is, say, 1:10, will be offset from the centre of the page outline 10 times the distance. The only fix is to have the origin at the centre of the page, most accurately set in a 1:1 or greater (e.g. 10:1, not 1:10) scale layer. Better yet, start with a new drawing, which automatically sets the origin -- of all layers -- to the centre, so that they are aligned.
