Hello ErLuiSS,
Thank you for your interest.
There isn't really an error. I know it is not the way you expect it to work, but if you go to the Nuggeta Developer website.
Go into Social and click on the Leaderboard.
You see the exact same list with reoccuring playernames. The only effect you have is when you set the properties of the Leaderboard to only overwrite = create new entry in the leaderboard when the score is higher/lower (according to order)
So overwrite on their website is really creating a new entry in the list.
From the extension we give you the result from the Leaderboard. You have to split the data into columns yourself. And also find the highest/lowest score yourself. Maybe we change that for a future release but then we might need a 2D List and that is done in other extensions.
Hopefully I tried to explain what is going on and you are able to split the data yourself.
Edit: On my way over to work I realized I was addressing maybe another issue rather than the one posted. I will investigate and come back with an answer.
Best regards from
M.E.
