I see no immediate issue with transaction cf7ad170e2f58aea83686095607b12a04cbef15679383a11c124d953bd2c5a6d which paid 749sat to 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so with a transaction fee of 1358sat from a native segwit address bc1qt2kyv6fuyq5xjutn7wkhn3ztwwzs52hdxd9zxn. If the transaction were somewhat invalid, it wouldn't have been mined and confirmed.

I have no idea what you're talking about. How about you make a screenshot of what confuses you, upload it to https://talkimg.com and post it with more context and explanation what you don't understand?
