I tried it myself and I also saw single quote. The problem is that all price fields (open, high, low, and close) are same and because of that the candle is not well formed. I have now made a change in Stockalyze to show a small dash in such case. You can try with latest Stockalyze. If you change the chart style to Line or something else then also you can see the complete chart.
Please let me know if it works for you.
