Components in Layout moving after applying to other documents

Hi, Bit of an intermittent issue that we've run into on a production server, but we haven't been able to figure out the cause. We have a document that's about 2 pages long, and it's used to create a layout. The layout looks fine. When we apply this layout to a copy of this document (all the text is in the same place and hasn't moved), the fields and signature boxes are all moving. They're not moving much, most are just moving a little bit in the minus-y direction, although one moves in both minus-y and positive-x, and another initial box at the bottom left of the document doesn't move at all (maybe because it can't move any further in the minus-y direction. We've never run into this before, but it's certainly happening consistently for this particular layout. Making a copy of the layout and applying the copy to the document will have the same issue as well. Attempts to reproduce locally with a new layout created from scratch haven't been successful though. Any suggestions as to what the issue might be? Have other customers noticed this sort of intermittent behaviour at all? thanks, -Chris
