More then 2 DKIM Signature Help!

[laurencesch]

So i am setting up my email side of my cwp and everything passes the checks on mail-tester.com except for 1 thing i get the following error.

You have more than one DKIM signature in your message.
Please enable only one signature, you should let your mail server sign the message and disable DKIM on your Newsletter software.

How can i remove 1 of the DKIM signatures?

the best would be that last sending mail server has dkim only.

Is there a solution for 'You have more than one DKIM signature in your message.'?

I am having this issue after purchasing CWP pro!
I have rebuilt Mail Server, rebooted server, reinstalled DKIM, deleted server DKIM but still have problem.
