Duplicate email headers

I have installed PHPlist 2.0.19

The problem I am experiencing is that email headers are being duplicated - it has the first received part but the second received part with “mail server server and helo” is missing

Version 2 is no longer supported, you should consider updating to the current version of 3.3.1 as it is far more secure.

I found 3.3.1 difficult to use

If you could point me in the right direction as to why email headers are being duplicated

Sorry, no longer have access to version 2 installs.

Could it be apache that is causing double headers?

I’m going to attempt to install 3.3.1 and see if it stops adding a double header

What if I can send you my login details
