Confused about Telegram Wallet Earn.

I'm confused because I deposited $643 in my Wallet Earn in early June but I had not created/activated my TON Space until yesterday and then I verified my ID. As soon as I did that a reward of 4.156 TON appeared in the TON Space section and I was able to claim them successfully and send them to my TON wallet on Binance, However, according to the APY proportion, I should have much more than that amount of rewards. I was supposed to get 50% for the first 2 weeks then 25% for the next 2 weeks then 15% for the next 2 weeks and then 5% until the end of the campaign. I'm think that those 4.156 TON I received were 5% and if that's the case, then what happened to the 50%, 25% and 15% part of my rewards? when will I receive them?
