Zero fret on Shawn Lane excalibur

[leon13]

I recently got a zero fret which I ordered through email.  I was able to remove the old one and replaced it with the one I ordered but it looks like there is a raidus on the zero fret.  Shouldn't the zero fret be also flat for Shawn Lane's guitar model?

It is the wrong fret.
