The night hag skills bonuses are calculated incorrectly. To explain, the proficiency bonus for a CR 5 monster is +3.
With a Charisma bonus of +3, Deception should either be +6 (normal) or +9 (expertise). It is incorrectly printed as +7. With a Wisdom bonus of +2, Insight and Perception should either be +5 (normal) or +8 (expertise). They are incorrectly printed as +6. With a Dexterity bonus of +2, Stealth should either be +5 (normal) or +8 (expertise). It is incorrectly printed as +6.

Interestingly, this is only a problem for the night hag. The night hag (coven variant) has its skills displayed correctly.
