Logrotate running at wrong hour/time
You seem to have overlooked /etc/anacrontab, where anacron finds when to evaluate /etc/cron.daily (and others).
Also, one of the many reasons I stay away from systemd. Check the first lines of /etc/cron.daily/logrotate:
# less -X /etc/cron.daily/logrotate
#!/bin/sh
# skip in favour of systemd timer
if [ -d /run/systemd/system ]; then
exit 0
