php-fpm74 systemd warnings on extranneous lvalues

I recent installed php7.4 in the php selector

It seems to be working properly, however, the php-fpm74 unit file seems to contain a bunch of unrecognized

systemctl status shows :

As compared to the php-fpm73 unit file which does not contain all of those extra lvalues

I could probably copy the 7.3 unit file over 7.4 and tweak it, but like I said, php 7.4 is working
