This latter is controled by a subscriber option (last option):
"Avoid duplicate copies of messages?
Avoid duplicate copies of messages?
When you are listed explicitly in the To: or Cc: headers of a list message,
you can opt to not receive another copy from the mailing list. Select Yes to
avoid receiving copies from the mailing list; select No to receive copies.
If the list has member personalized messages enabled, and you elect to receive
copies, every copy will have a X-Mailman-Copy: yes header added to it. "
Default for this option is "Yes".
The From: munging is part of the DMARC handling (General Admin Options):
"Replace the sender with the list address to conform with policies like ADSP
and DMARC. It replaces the poster's address in the From: header with the list
address and adds the poster to the Reply-To: header, but the anonymous_list
and Reply-To: header munging settings below take priority. If setting this to
Yes, it is advised to set the MTA to DKIM sign all emails.
If this is set to Wrap Message, just wrap the message in an outer message
From: the list with Content-Type: message/rfc822.
You are seeing the "Mung From" option behaviour.
