As you know Stockalyze uses data from Yahoo!, Tiingo, or Alphavantage. If the data provider misses a record Stockalyze cannot do anything about it. You can check on Alphavantage website and download the data of your stock and see if it has same data as Stockalyze shows. If you find Stockalyze shows different data, which I very much doubt, then please let me know.
