Cavalier Emissary Typo?

[Nixius9]

I have a player currently playing this archetype. At seventeenth level, the emissary gets Erratic Charge in place of Supreme charge. Supreme charge is a 20th level ability, and the reletive power of Erratic charge suggests it should replace it at the 20th level. Up until this point, the emissary has been getting Tactician abilities replaced and the seventeenth level ability that Erratic charge now lands next to is Master tactician (not very valuable without it's predicessors.

Should the book read "replaces Master Tactician" instead of supreme charge, thus giving the player both charges, Or should it read "At 20th level..."?

Also, if the latter is the correct way this should have been presented, what to do with Master Tactician?

Currently, I gave the player Erratic charge at seventeenth level, dropped the Master Tactician, and gave them a bonus feat at 20th level.

Based on the evidence, I'd agree it should probably replace Master Tactician. Wouldn't make much sense to give them the highest Tactician ability without the lower ones, while giving the two lower charges and not the highest one. While good, I don't think it is so powerful as to need to replace both abilities or anything either. It is 17th level, after all.

This is post errata and the question stands, what do you do with Master Tactician?
