Autofill in Simplii Financial website shows credit card details instead of user and password

Options

At the login website for Simplii Financial (https://online.simplii.com), the 1Password autofill functionality (drop-down options) only shows the list of available credit cards in 1Password, but not my user credentials for Simplii.

Simplii Financial requires every user to enter their card number and password.

As soon as the user clicks in the card number box, the only options that the auto-fill drop-down menu show are available credit cards, but not my user credentials for Simplii.

Workaround: click on the 1Password browser extension and then the regular credentials are offered, on top of the available credit cards. Select Autofill in the right account login and voilá, it works.
