PHP Settings Resorting to Defaults WHM

Hi, I'm having an issue with WHM - I've added a custom line in my PHP settings for 7.2 through MultiPHP INI Editor Every few days to a week, this will default to the original php file and remove my changes 1. Where is the default php example stored so I can change it at the source? 2. If that isn't possible, how can I prevent this? 3. Why does it do this? Thank you /etc/redhat-release:CentOS Linux release 7.7.1908 (Core) /usr/local/cpanel/version:11.84.0.18 /var/cpanel/envtype:kvm CPANEL=release
