Is it fine that I chipped off a bit of my backhand rubber?

When I was practicing serving today with my new blade, I accidentally hit the edge of the table with my backhand rubber, a small part on the upper part of the rubber came out.

Yes, absolutely. It's required to damage a new rubber a bit, otherwise it won't play well 😁

Seriously it doesn't matter as long as the hitting area is intact.
