None of these conditions are real issues, but they can simply happen because we just swtched from /run to /var as backend for logging and there are old files from different boots with different systemd versions and so on. Let's not make more noise than necessary: still log, but not consider it a warning, but just some normal thing. We are handling these issues safely after all: by rotating and starting anew, i.e. there's no reason to be concerned.
