Can the California DMV remove a reckless driving charge on my record that I was never actually convicted of in Hawaii?

I went to court for speeding in Hawaii. I got a lawyer and he told me to plea for reckless driving and ask for a 6 month deferral. The deferral was granted, so essentially, I deferred my plea. It was dismissed earlier this month, after the 6 month period expired, but the DMV has a "conviction" of reckless driving for 2 points on my record. It was my understanding that I was never convicted, which is the entire reason I went the route that I did.
