If I look at my transactions I can only see where the transaction came from. The 'account' is just a name which I gave it and when I click on the account it shows a different receiving address. Also the address isn't listed on the Receiving / Sending Addresses overview.
You will have to join the new slack, they will have a support type channel where this can be answered. I don't really need to know my old addresses, I was just told create accounts and save your recovery phrase.
