Firefox Extension won't auto fill Gmail addresses

Using latest version of firefox on windows 10

Gmail addresses are showing in the 1password extension, but when I try to log in, they do not show up in the drop down, I have to manually copy paste ID and Password.

I have manually removed and added them again, but still not showing in drop down.

Please help.
