Assigned vault preference feature does not seem to work.

I think I found the source... I had not set the extension prefs to record password changes to our shared vault. It was set to record changes to my Personal vault. I changed it a few hours ago to record to our shared vault. BUT... I have a question... when I just looked at the extension settings to verify how it was set, the "Accounts & Vaults" setting is now "Locked" and it says above it "Include in all vaults". That implies changes will go to both vaults. I don't know how it was locked and I don't see a way to unlock it.
