"You can also try that to check if you can reproduce those addresses into your blockchain(dot)com's unused addresses list." Could You, please, send the hint for this to be managed?
Note that if you clicked the "trash can" icon to delete the address in the blockchain UI:
You won't be able to "recreate" that address in Blockchain. Having said that, it shouldn't matter... if the address was from that wallet, it should automatically show in your balance and/or in the "used" addresses section (You may need to click the "Reveal Addresses" button)
All of this is under the "gear" icon and then "Wallets & Addresses":
Then click the "manage" link on the right hand side of the screen for the wallet you're trying to get the addresses from:
Speaking of... how many wallets are actually showing in that list for you? Do you only have one or are there several?
