Some address appear twice, also the percentage for votes seem wrong, on Safe space, 33 votes should mean 100% since there been only 33 proposals

There are 20k votes on safe space, vote percentage is relative to total number of votes, not number of proposals

@wa0x6e It should be relative to the number of proposal, this is to get the participation rate, % of all vote is not much relevant insight
