Auto CC is Off but still sends email

Auto CC is Off but still sends email

Hi, I often forward an email from my work address into the ticket system using my custom support@xxxxx.zohodesk.com  email.
Even though I have the Auto CC email replies to my support box Off (image attached), It still includes that when I reply.
And if i forget to manually remove it, i then get a reply to the ticket a moment later which just makes false alerts to tickets.
Why is it doing that and how do i disable it never to CC anyone but the original email address(s)?

Also related, when I do forward and email to the ticket system, If it was an email with more than one person CC's in it, I would want them all to be on the ticket but it only takes the original sender. Then I have to remember to go through the email and copy and past all the other people into the CC. Is there a way for it to take everyone's address that was on the original email?

Seems like obvious things that are just not working but I cant find a solution in knowledge base or playing with settings.

Any suggestions would greatly be appreciated. :)
