Bug - Error message received even if checkbox ticked

https://www.nseindia.com/products/content/equities/indices/historical_pepb.htm

On the abovementioned page, even if checkboxes are ticked, an error message is received saying “Please tick at least one check box.”

The page works fine in IE and Chrome browsers.

Error msg is received only in Comodo in both win XP and win 10.

Thanks and regards,
