Hi.

You have probable misunderstanding how the Link Password work for muliple encryption of the same bookmark.
Link Password have two modes for encryption bookmark that already is encrypted (Skip already encrypted bookmarks).
* Skip encrypting: Then all unencrypted bookmark will be encrypted with the new password and old bookmarks will be encrypted with the old password.
* Encrypt again: Then all bookmarks will be encrypted with the new password, and if any of the bookmarks was encrypted since before you will have to first providing you new password and then providing the old password.
