Yamaha chrome stick’em letters?

Just got my brand new grizzly home the other day. I took it out that day to break it in,and took it out today for some putting around with my son. Hit a few puddles and got her all dirty,so when I got home I rinsed it off,as I was toweling it off I seen thing on my floor board. I picked it up and it was my Yamaha chrome stick’em letters,like 3 of them just came off,and it looks like the rest of them aint far behind.
Not a big deal,but it did kinda bum me out,I didnt even spray it up that high,I must have just brushed the towel over it. I was just wondering if this is common? Like I said its not a big deal,but I assume they would stay on there longer that 2 hours of use.
Also I only got one key with the grizzly,should I have gotten two from the dealership?
Other than that,Im really happy with it and getting ready to give it its first oil change and do some more riding sunday!
