March of Fury not Working

It seems my March of Fury is not working, I upgrade it by March Capacity stays the same. What did I do wrong?

Most common mistake here is that players do not realize they need to assign the Airship Ability to each activity they want to extend the March Capacity in the Airship Dock. This can be done (via Airship Abilities - Assign Abilities) for the Attack, Gathering and Beast categories. So if you just assign it to Attack and not to Beast and you attack a Beast or Red Guard, your March of Fury increase will not be used.
