Closing Price in Monthly and Weekly Charts for Latest Candlestick

The Closing Price of Daily Chart matches with NSE Closing Price of the trading day.

However, when I look at the weekly and monthly charts, I see that the Closing Price is different from the Daily Closing Price.
I am looking at the charts at after trading hours or on weekends. So, it should all be same, right.
It only differs for the Latest Candlestick. Rest all candlestick matches with NSE data.
Kindly explain, what is the calculation of the closing price of latest candlestick for weekly and monthly charts.

Many Thanks
