Lost xETL my referral friends

good morning everyone today I sent a friend of mine to participate in the airdrop and he also bought xETL with bnb. The transaction was successful but does not display the xETLs in etherlite mainet in your wallet this is hash of the transaction su bscscan

I wanted to know if I earn 5% of what he buys I ask you why the person who invited me didn’t earn anything.

Help please
