No reward for leveling up

I've started playing Apex again recently, but my level and some of my stats are gone. What's more, there are no rewards for leveling up, and I can't buy new Legends to play with. I still have all my currencies and heirlooms, so I don’t think there’s anything wrong with those. But I’ve spent quite a lot of time playing with the Legends I already own, and honestly, it got boring really fast.
