Those are bech32 (native Segwit) addresses. They are not supported by the block explorer you are trying to use (Blockchain.info);
Either use a different explorer that supports it (e.g blockchair.com) or create a wallet with nested Segwit addresses (starting with a 3 and which are supported everywhere).
Here is a tutorial for that: https://bitcointalksearch.org/topic/m.36735893
