I began a trial of 1Password for myself. After determining that it worked, my family signed up for a family account. I recognize that I can't merge my private account into my vault of the new family account, but neither will the software allow me to copy them over, either through the copy function, or through exporting and importing.
When I select an item from my trial vault (either singly or all together) and select copy, it offers me the new vault as a destination location. But when I select it, nothing appears. The same happens when I try to import to that vault—nothing happens. In fact, I was just now trying to make a login in the new vault to see if I could copy in the other direction, and 1Password seems to be reliably crashing when I try to save that new item.
I'm going to try uninstalling the app next.
