New Reward Bug?

What you were expecting to happen, and what actually happened?

I wasn’t expecting a new reward and I got all that I already had.

What are the steps to make it happen again?

Won a PvP battle - this has happened twice in a row this far. The first time was after I leveled.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
