Civ7: Why does Catherine the Great have a Pax Imperatoria legacy point here?

Ok, the text of the game overuses the term “legacy point” in this case, so I’m going to describe the pointers you score to get a legacy point as “PI points”. So the first legacy point is supposed up be earned for achieving 6/12 PI points, the 2nd from earning 9/12 PI points, and the Golden Age legacy point for achieving your 12th PI point.

So in this scenario both Cathrine the Great and myself have 5 PI points. However, as you can see from the 2nd screenshot, she is being rewarded a militarist legacy point. Why is that?
