Right click on the Fibo and Select “Edit Point”. Move the cursor horizontally. As you pass Fibo Points, they are highlighted (red circle).
When the point you want to change is highlighted, just click on the day you want to select as new point. If the cursor is above the middle of the candlestick, the new point is the High point of the candlestick; if below, it’s the Low point of the candlestick.
