On a weekly or monthly chart, the last period could show two candles: the real one, and a thin extra one for its latest session. Our price source sends that session as a row of its own.
That row is now folded into the period's candle, so a week or a month is always one candle, with the latest price as its close. Daily and shorter charts were never affected, and your trades and drawings are unchanged. If you still see the old candle, reload the chart.
