Hey @jasonpraful 👋
1Password 8 includes a duplicate finder through Watchtower, try these steps:
1. Open and unlock the 1Password for Mac desktop app.
2. Click on Watchtower in the sidebar.
3. Click on Show Items under Items with duplicates.
The duplicates remover tool will only look for items that are exactly the same and that are located in the same vault. You can read more here: Use Watchtower to find account details you need to change
If that doesn't work then can you tell me a little more about the items that you're seeing? Are they perfect duplicates of each other? Or do they have slight differences? Are they located in different vaults?
