Why in some websites 1password doesn't automatically fill ,y login details ?

ronen,

On behalf of Dave, you're welcome. I'm glad to hear that it's working as expected. You mentioned:

Sometimes 1Password is filling only my username and not the login's password. How can I update 1password to fill all login details ?

May I ask which websites are you experiencing this on?

Also I don't understand why there is 2 1pssword options in the popup menu ? Thanks.

I'm sorry for the inconvenience. This is a known issue that our development team is currently investigating. I've added you as an affected user to our internal reporting.
