from and reply-to fields

In my form’s settings I’m using the email field id “{{nm_field_3}” for the “from email” but it’s defaulting to the admin email (although the email it’s using is my old admin email which has since been changed).

I’m also having the same problem with the reply-to email setting. For the reply-to email setting it says,

…fallback to admin email. Default is sender email.

So, if the email field is not a required field and is left blank, the admin email will be used otherwise the sender email will be used? Is that how it’s supposed to work?
