This happened today too. Before zooming out, the candle is different, and after zooming out, the candle corrects itself. I have provided the screenshots below.
Also, if it helps to resolve the issue, i am not sure but i think this happens when the chart is kept open before the market opens. Then the first candle is almost always wrong. Could you please check and have this resolved. Thanks.
