On the world map, not in tactical combat. I'm not sure if the issue is specific to the Compass item thingy, or if it's a general thing. Whatever the cause, the stack's movement allowance occasionally displays wrong in the stack info, and/or the stack doesn't get the movement allowance bonus from the Compass.
Related, I'm unsure whether the Compass is supposed to be a unique item or not, but I've currently got two of them.
