Portisch-Petrosian Lone Pine error

I was just doing this game on the training and have spotted a mistake after ---g4+! 2 Kf2 black's next move should be Rh7 rather than h4 followed by 3 Rd2 then h4 rather than Rh7 black's moves are the other way round.  I checked on another web site which lists the games and confirmed it as correct.  I don't know where to register this with 'staff'.  Can anyone help?

regards

ps I've sent a request for this to be looked at by staff in the help and support section.
