In MCX on the day of expiry of a future sometimes close is less/more than the low/high?

As seen in the bhavcopy available on mcx the low is 1140 while the close is 1127.8 

And in this case the close is more than high for a gold future

Both of these are on the date of expiry of future, can some one help me understand what I am missing here.

The close is the settlement price which converges with the spot rates. High/Low are the trading rates based on how the price fluctuates during the day.
