Steam leaderboards not working

So, I am trying to work with steam leaderboards from BP. Here’s my code (made just for testing)

I have also read [this][2] and [this][3]. I have also setted up My SteamApp id, and also created 2 leaderboards in steam (test and test_test),

just like stats (test and test_test).

And when i pressed “O” in standalone game, the only thing i got printed, is “Nothing”. No success, no failure. Any idea?

P.S. Also i have tried the modified engine (modifications described [here][2]), but nothing has changed.
