Input boolean - no logbook, why?

I have two input booleans - both created around the same time and configured the same. One shows log book entries and the other says nothing found. Yet both devices are being triggered as I see it in the history.

I checked the Home Assistant Core logs and I don’t see any errors related to this boolean or around this time.

So what can I do to get the log book working for this input boolean - delete and recreate? Thanks.
