Historical data: Godrej consumer products data does not seem to be adjusted for the bonus

Godrej consumer products stock was adjusted for the bonus on September 13, 2018. The daily end of day data provides the reduced prices after September 13. I was assuming that if I download the entire data from 2015 onwards, it would be adjusted for bonus.

According to this thread, the stock prices are adjusted for corporate action after every week

But I'm not seeing that. The stock price for end of day data continues to be approximately Rs. 1200 before the bonus and Rs. 700 after the bonus.

Can you please suggest when this will be corrected?
