Hi,

If you're experiencing game shelf related glitches can you try going here:

https://secure.gog.com/account/refresh

Don't worry, it's just an url that will do a quick "refresh" of your account page, nothing more :)

If you still experience bugs after refreshing your account please use the Support link on the top of your browser and send our Support department an email with your issue and you should be taken care of right quick :)

Thanks :)

Also, try not using the list menu, use the shelf version instead and see if that works :)
