I have been having an "issue" where 1Password is not able to fill in the password and one-time password token automatically. This occurs for the Backblaze.com website. Nothing appears to be pasted for the password.
Admittedly this is a first world issue, and I can copy and paste from the browser plugin. Just thought I would pass this along.
I have also have a similar problem where the token is pasted as the password.
1Password Version: 7.5
