Multiple logins for site - 1Password autosubmits first one always
I'm using the latest version of Firefox (verison 26, right now) on OS X 10.7.5, with 1Password 3.8.
I have multiple Gmail accounts saved in 1Password and it was working fine for the last few years. Sometime ago I added one more Gmail account to the list and now anytime I visit Gmail and hit Cmd+\, 1Password fills and submits one of the logins without prompting me with the list of logins to choose from. This does not happen on other sites where I have multiple accounts (where it shows me the list of logins for the site and waits for me to choose which one to autosubmit). I'd like Gmail to also behave similarly - 1Password should list the accounts I have and allow me to choose.
I'm probably overlooking some simple option or setting. Any help is appreciated. Thanks!
