While it's no a big problem, if you're like me, it will bug you. here are a few things you can try:

First, if you have a heat gun, carefully bend it the other way and apply heat to both sides.

Or, try putting a thin shim under it and weighting down the ends (ecentially bending it the OTHER way) and let it sit overnight.

But, as said, if neither works, don't worry about it.
