Scoreboard - Official Wiki: Stat declared in history but not table.

Some information in the history section of the scoreboard page is missing in the actual content of the page.

Particular examples:
14w30a - Added the stat.talkedToVillager and stat.tradedWithVillager objective criteria.

This example is present in History but not the stats section of the content.
This example is not confirmed to be limited to this page only nor this incident only.
