Issue with sending domains

I have the sending domain setup but outlook still shows the sender as where is the domain sending the email not the domain set as the from email. My only solution seems to be putting the mailwizz software on the domain its supposed to be masking for.

Also the sending domain is verified.
Forgot to mention this one is my fault I had from address set to forced use instead of check if sender domain is valid thingy. Fixed it on my own :)
