In our Service Management project, there is a ticket which supposedly was raised by me via Jira (see screenshot)

In reality, this ticket was raised by a customer via email. Usually, our project handles this correctly, and puts the sender of that email in the reporter field.
Why is
a) the reporter wrong in this ticket?
b) the ticket listed as raised via Jira, rather than being correctly listed as raised via email?
And what can I do so Jira Service Managament handles this correctly in the future?
