I'm running 1Password 6 (Version 6.8 (680015)), and Safari 10.1.1 (12603.2.4), on macOS Sierra (10.12.5).
When I use the keyboard shortcut (⌘-\) to bring up the mini browser. Unlock with my master password, and it shows no entries. Hit ESC, then "⌘-\" and there are my options. I can lock the vault and duplicate it time and time again.
I tried uninstalling and reinstalling the extension with no luck.
Anyone else? It's mostly a minor inconvenience, but thought maybe others had seen it. Definitely caused a moment of panic when I thought my vault disappeared.
