Report a BUG : Which the Energy Regeneration Runes not working right during the in-game play.

Last night I bought three purple Energy Regeneration Runes to match my new Build for Lee Sin,

after I finish building my runes, it showed three of them should gain me 4.7 energy regeneration per five secs.

So I started Que, picked lee, picked my new runes, then I was surprised by my new runes, it displayed I can only gain 0.9 energy regeneration per five secs instead of 4.7 !!

First, I thought it was the displaying text went wrong, but it ends up I was wrong, my new runes only provide me 0.9 energy regeneration during the in-game play！！！

Question : 1. Can u RIOT guys have a look of this and fix it pls ? 2. Is there any reward for reporting an in-game Bug ? If so, can u guys pls gifted me a RIOT Graves Skin Shard pls ? ( Really want own that damm skin pls RIOT! ) XD

Thank you
