Humble Bundle Region Keys restrictions

Hello,
Recently i notice that some of the keys, part of the Bundles in Humble Bundle, are restricted for activation in EU only. I've contacted theyr support with the question .. why some of the keys are EU and some are Global. Theyr answer was something like "All the keys you've got after purchase are for the region of which they are purchased"...which in my case is EU. I know that's just not true. I am theyr client since first months of humble bundle and 95% of the keys, for the games, i've got are Global.
My question is..is there a way i should know which games, part of a bundle, are EU restricted and witch ones are global without activating the actual games in Steam ?
Maybe someone..or somewhere ( a site ) that usually buys from them, activate the keys..and them post some information about it ?
Thank you in advance.

Greetings
