Unable to find the addresses created before enabling shared address

Hi,

We enabled shared address recently in our staging instance. I could see the Address related section displayed in the Accounts page. Also the account addresses are visible in the address related section (address names are defaulted to the address id).

However when I navigate to the Address tab/screen, I couldn't see these addresses which were created before enabling the shared addresses. The new addresses that are created after enabling the shared address are visible.

Searching by address name also doesn't pull any records.

How can I query the addresses that were created before enabling shared address?

Once we create all addresses as shared addresses (using Data Import Export tools), how can I delete these old addresses?
