How to customize the email subject for a webform?
So, I think you're using the UI wrong. Each of those email templates you have should be to a different user and it doesn't look like you've added an email to anyone.

Below where you have your Value of "Event Type" line there's the option to send an email to a specific email address (I.E the admin) or to add an email to the value of the Email token, you need to add and save an email to a specific person there and add a subject using your token substitution there. Or at least that's what it looks like from what you posted.
