Reply to email submission includes the original destination address

We receive emails to multiple email addresses like support@ourcompany.com and services@ourcompany.com.

Scenario
Requester submits a request email to support@ourcompany.com. When we open the request and try to reply to the ticket the to field has the requester's address but the cc field has our company address, support@ourcompany.com. I can't find any setting to stop this from happening or any setting that would cause this.

This is causing problems when we go to resolve the ticket. The ticket is getting reopened due to the message going back to servicedesk. I am hoping someone has a solution to this as this is a pretty big problem for us. This does not seem to happen if the user just closes the request.

I have attached the history of a ticket that was closed and then reopened by the system due to a conversation being added. I need to be able to email CC users since interested users are frequently CCed.
