If the stance buttons are toggles, good UI/UX practice would be for the buttons to change color or shape when active so that you can tell by looking at them and nothing else whether pressing them will turn something on or off. It would be a good thing if this is how they handled it.
However, we have some conflicting signals here. The updated Job Guides don't show "This button cannot be assigned to a hotbar." so maybe they are extra buttons. It would be better if they are still the same buttons, just color changing to indicate state.
