**Your software**  
My Mautic version is: 4.1  
My PHP version is: 7.4  
My Database type and version is:  
mysql Ver 15.1 Distrib 10.3.31-MariaDB

**Your problem**  
My problem is:

There are multiple values in List-Unsubscribe header of the emails send through Mautic:

I suspect due to this Gmail is not showing the unsubscribe button which it normally shows right next to the sender email address.

Does anyone know how to fix this?

Thanks
