Fill price way outside of OHLC prices in paper trading

I was trading AMAM last week using the paper trading sim. I’m interfacing using python API and using market orders. The OHLC for a one minute candle was 1.35-1.55. However, when I placed an order I was filled at $10 at 1326 shares (I’m limiting the amount I trade to ~$2000 right now, so this shouldn’t have happend). I sold about 10 minutes later around $3.23, which should have been a great return however, the paper trading sim is showing a loss about $8000. Is this a bug in the paper trading market data? Just want to make sure this doesn’t happen during live trading. Thanks.
