having issues with gamekiller topic

Hello, I'm having problem with my gamekiller app, everything is fine but I was wondering why I have no 'modify all values' in data control. I know im supposed to try and change the value of the thing im hacking but im hacking a in game shop of which the values cannot be changed and there are a ton of results, so can anyone explain why I don't have the ability to modify all values and can someone please send me a link to gamekiller version with this option, any answers are welcome, thanks for reading my concern. :)
