[syslog-ng] syslog-ng won't talk to systemd?

I'm trying to setup syslog-ng on a systemd system. But even though I 
have several things writing to syslog, syslog-ng doesn't write ANYTHING 
to the /var/log/messages except kernel messages and it's own info. So I 
searched around, and found the systemd-journal() source. So I tried it. 
And I get an error that says syslog-ng can't initialize the logger plugin:

# syslog-ng -F
[2021-01-23T23:25:36.525097] The configuration must not contain more than one systemd-journal() source;
[2021-01-23T23:25:36.525157] Error initializing journal_reader;
[2021-01-23T23:25:36.525173] Error initializing message pipeline; plugin_name='systemd-journal', location='/etc/syslog-ng/syslog-ng.conf:26:5'

Here's the config, basically copied from the syslog-ng.com page:

@version: 3.26
# Syslog-ng default configuration file for Gentoo Linux

# https://bugs.gentoo.org/426814
@include "scl.conf"

options {

source s_journald {



source src { system(); internal(); file("/proc/kmsg"); };

destination messages { file("/var/log/messages"); };
destination console_all { file("/dev/tty12"); };

log { source(src); destination(messages); };
log { source(s_journald); destination(messages); };
log { source(src); destination(console_all); };

What am I doing wrong? I am POSITIVE things are sending to the syslog 
sub-system. I have ensured several programs have sent something. But 
without the systemd-journal line syslog-ng loads fine, recording 
/proc/kmsg and syslog-ng messages but nothing else.

I am completely stumped here.
