Sorry for my late reply, I was waiting for the MT4 technicians to double check with our Liquidity Providers before I reply.
From what I have been explained there is no error, it was one single tick which occured at 00:00. The reason the spike is not there on Dukascopy is because each broker or bank uses different liquidity providers which posses bigger or smaller liquidity at different times of the day accordingly.
Thank you,
