Yeah, I was washing mine the other day and noticed the same thing. I was going
to post a question about it once I had searched to see, but I haven't gotten
around to it really yet, so I'll just post here saying I have the same problem.
Also mine seem to have the very tip of where it rounds up to meet with the fender
sticking out as well as not matching up (not really any sagging but more just
not exactly lining up).
