I've not noticed a problem with our Campscout, yet.
I did not work in the construction materials area but I do know that Styrofoam has been bonded to floor boards and sold for use separately under floor boards for a long time (ie Dow Floormate). In the van, if the surface below the styrofoam is uneven (ie ridges of sprayed foam), that may cause the problem since it would not be fully supporting the foam layer... of course, I could be very wrong !
However, since the van is well within the warranty, I would suggest that it is really down to Globecar to figure it out and solve the issue.
