Hi David,
Are you trying to import only logins or also other types of records?
The 1Password import feature currently supports only the import of the logins. Other types of records (notes, credit cards etc.) are skipped.
Also, while importing the logins, the application skips all duplicate records (The records that have exactly the same username, password, service name and url) to keep the vault clean.
Is that what you have experienced?
Regards,
David
