Voting All Stars 2016 - missclick

Dear Riot Support and fellow Gamers,

So I was voting for the All Stars and accidently clicked on confirm after I only voted for EU LCS, now when I refresh and wanna vote for the other LCS Regions, it doesnt work anymore.

Is there any way to reset my Votes and to re-vote again? If yes, will I still get the Icon reward for voting after the Reset?

Thanks in Advance,
