Many duplicates after upgrading to 1password 8

Sounds like this duplicate problem is widespread. Does the migration from 7 to 8 move all vaults to one vault? Currently have 2 vaults on Dropbox and would like to keep them separate. I downgraded to v7 and did not see dups, so I may have accidentally migrated twice. Can I move to v8 and still have two vaults and have another family member access both vaults separately? I think your solution is to have two separate accounts, or perhaps one family account. Again, the objective is to have two separate vaults that can both be accessed (from anywhere) by two family members.
