Update Credentials with Fastmail

Hi, I'd like to know if this behavior is normal.

I'm trying out the FastMail integration and I ran into a behavior that to me is weird.

Here's an example:

I have an account at Domino's, they love to spam me, so I figured I'd start there. The account was with my original normal e-mail, and I updated it with an alias from Fastmail using the browser UI. So when I clicked the email field on their website, the suggestion at the bottom of the email field suggested creating an anonymous email. Once I clicked the button the 1Password window showed up to update the credentials. There's only one problem.

The credential now has both emails, the old one is saved at the default username field, and there is one new field named email, with the FastMail alias. Do I need to manually fix this for each website I update?

Also during that edit window where you check the changes before confirming, It's impossible to delete the old username field (probably because it is a default field).
