Were you the one that sent the transaction? From what I can tell, the block explorer didn't make any mistake. The address you're seeing is a bech32 address (bc1 prefix) and it is a standard for native segwit address and it's perfectly valid. The only reason why you can't parse the address on various block explorers is because they don't support it yet. Blockchair.com does support bech32 address.
No No..That address is from among the one I'm tracking here

To my knowledge, no block explorer actually displays the public keys involved. They can be derived from the redeem script.
Thanks.I'll figure that out!
