Voting keys not given

[Pevte]

As in the title I didnt get voting keys twice when I voted on topG page. Also there is no possibility to type nickname when you are voting on that page. Is there any solution for that?
I appologise if its not the right place for this question,but I didnt know where should I write it.

Also, https://minecraft-server-list.com/server/424827/vote/ when I try to vote on this page it says that my name is invalid so I cant vote.
