Items With Blank Fields After Sharing B/W Vaults

Hello,

I created a vault in 1Password 4 using a backup file from the Windows version of 1Password (1.0.9.340). When I would try to share an item from that vault to my primary vault, the item would appear, but all of the fields within it would be empty (except for "website" and any attachments).
This was also the case when I tried to merge the vault with my primary by importing the .1pif file of the vault - all of the items would show up but the fields would be empty.

I later figured out that I needed to select and share an item twice before it would be properly imported to my primary vault. Is this how the application is suppose to behave? Did I miss something?

This only occurs when I try to share items from the vault I created using the backup file from the Windows version of 1Password.

Thanks,
Lakey
