Change "from" email to attendees

The “from” email address sent to attendees to confirm their tickets, how do I change it? It seemed to be pulling from the “WP Admin” email address, which was my personal email. I changed that to the professional email but it’s still sending “from” my personal email (which is not professional at all.)

Please help!
