How to export secondary vaults?

I am having trouble exporting my 1Password vaults.  I have a families account and have secondary vaults for each family member.  When I export my family vault, I only get items exported from my default vault.  This happens even if I have view + manage set for all of the secondary vaults.  When I export a secondary vault CSV and go into the excel file, none of the items from the secondary vault are there.

I have tried clicking on the vault, then doing the three dots, then export.  I have tried changing the default save vault then doing the three dots then export.  All of them just export my primary vault.

What am I doing wrong?

I am using
1Password for Windows 8.12.6 (81206039)
