Your little snippet shows no copies of weewxd running. What you're seeing
is your grep command.

Let's get  a proper log to work with. Don't use systemctl status weewx. It
just doesn't show enough context.

Set debug=1 in weewx.conf, restart weewxd, let it run for a reporting cycle
(if possible), then post the log. Additional details on capturing a good
log can be found here <https://github.com/weewx/weewx/wiki/view-logs>.
