Games : Receiving a player level 2 rewards on higher levels

Every so often after playing a game, the post-game screen suggests I just reached Player Level 2, receiving the corresponding 1000 gold reward. However, I am actually level 25. Is this a bug? Or am I missing some kind of feature?

Here's a screenshot of such a post-game situation:

And here's a screenshot of my Player Progression right after that:

As you can see, I am still level 25, have not just levelled nor am I about to (or would I get any reward if I would). Strange thing is (and I'm not complaining): it seems I get to keep the gold.

This happened to me on more than one occasion (about three or four times now, I think).

Is this a bug? Or am I missing something?
