Unable to remove API key/username and Password

I’ll preface this by saying I know how to delete the records and don’t need assistance but I wanted to point this out.

There’s many things screwed with the saving (and deleting of the API key and username and password).

1) You cannot remove an API key in the settings page
2) You cannot remove a username and password in the settings page
3) If you have both an API key and username/password – you cannot choose the user the username and password, the api key is always selected.

There should be a way to remove the API key, and/or username and password.

If anyone else is unable to remove their settings, go to your site /wp-admin/options.php and search (CTRL+F) for “Sendgrid” and you can empty any/all settings you want, like “sendgrid_user”, “sendgrid_api_key” and “sendgrid_pwd”
