I just switched from LastPass to 1Password. Changed every one of my 445 passwords using just the chrome browser extension. Never once ran into this issue, UNTIL I installed the standalone Mac app. Like others I saw on redditt, I discovered that quitting the stand alone mac app made the problem go away. Wanted to add my entry here for more info to the team. I'm on 1P7 on this 2010 Mac Pro, so can't update to 1P8 on this machine.
