I have this problem too, but it's a result of a bug in Enpass. I imported all my passwords from 1Password 7 to Enpass, and everything came over perfectly, but with one major problem: everything that was in my 1password archive is now in Trash in Enpass. And I can't just restore them because they'll get lost among the passwords that I want to keep. The limit in functionality is completely unnecessary here. In future updates could you allow us to move items directly from the trash to the archive? Currently there is no way to move my 111 passwords that were erroneously put into the trash directly into the archive. Is there any way you can fix this?
