Blockchain.info generated for me when i transferred x amount of BTC into it (before the hard forks) then i transferred all my holdings to another wallet after the forks. The thing is that i didn't see it in the used/archived addresses until i imported it manually and it is listed now for watch only
would you be willing to screenshot that address (and its txid) in your blockchain.info wallet? or tell us the address
is your account quite old? can you check on:
Settings >
Addresses |
"Imported Bitcoin Addresses"the address could be generated before the introduction of the seed and listed under imported address by default
