Passwords in family account Not showing

Hi everyone, I am part of a family account. My wife and I have our own  vault with passwords. My wife can see "all of them", but i can see only a subset.

History: I had my own personal 1pw account. I gott added to the family account and somehow had the app twice. Deleted the "old" app. All is fine, i could add, see and use all passwords in our vault. 

Then my mobile Phone breaks without backup, i reinstall 1password, use my security code and so on. Then I cannot see most passwords. My account gets restored by the family account's admin, but same story.

Any idea how i can get access to all the passwords again? 

Thanks in advance
