The dealer was making delivery of 2 vehicles when I received mine, and while he was chatting with the other folks, I started putting on my own plate and found the supplied screws to be too long. Glad the dealer didn't get a chance to touch mine.
Some folks have reported dealers running screws right through the sheet metal.
I'd take it back and complain. At the very least they need to take care of it so it doesn't rust.
