Arena Bug

Hello.

Every day I have some Arena bug where players are showing 2-3 times in the first 5 players. Most of the times I need to spend diamonds to refresh it if I want to do 10 times Arena, because it's not allowing me to attack the same player again. I'm uploading 2 screenshots from today, you can see the that I have 1 player 3 times in there. The server have enough players to change them every time, but it's not doing it.
