1Password does not stay unlocked

I want to keep 1Password unlocked on my Firefox browser but no matter the setting, it locks:

1. In Security, I have "Automatically Lock 1Password"  - turned Off (button is to the left)
       but if I leave my laptop for a few hours, when I return, it is locked.
2. In Security, I have "Automatically Lock 1Password" - turned On (button to the right). Next, 
   "Lock after system is idle for" , I've tried 8 hours or Never, and "Lock when device goes to sleep" is turned off (button to the left). However, after I've been away for less than 8 hours, 1Password still locks.

Thanks for any help on what I'm doing wrong.
