Have I ruined my board?

I just recently got this boos block chop n slice board and noticed some deep gashes after only a few uses. Then today after cutting 2 bunches of green onion, I noticed a ton of gashes and small chips in the board. Then I realized my knife was causing this. I don’t know how to explain it so there are pictures of the knife but I guess I must have caused this with poor sharpening technique using whetstones.

Can this board be fixed? If so, how?
