What does the warning mean?

In Kansas you have to go to the local Highway Patrol office to have them confirm the VIN. In the past few years, I have had 2 big problems with them. About 5 years ago, we bought a practically new RV in Arizona. It was less than a year old. When I went to the Highway Patrol Office, they refused to process my paperwork. They said the paperwork from the dealer was not in order, and that I needed the original title from the previous owner. The dealership was shocked. They told me they had sold thousands of RVs and their paperwork had never been refused. The Sales Manager talked to the HP people while I was there, but it did no good. It took 2 months to get a tag.
Then, about two years ago, I bought a Mercedes 500SL cheap at a Mecum auction. The same lady was not going to process my paperwork because the VIN tag was in the "wrong" place. She said it should be on dash by windshield. I proved to her online that it was in the door jamb, but she wouldn't budge. When I raised my voice a little, her boss came out, sided with me, and I got my paperwork stamped. What a pain.
