Have you equipped them with the WG42? If so, it may be that she reached the daytime damage cap (~150) and scored a critical hit for 225 damage in total, and the boss got unlucky with their armour roll. That would reduce the damage by 220 x 0.7 = 154, which leaves you dealing about 71 damage in total. As for why this hasn't happened in night battle, it's probably just bad luck. There may also be some errors in the damage formula, since we don't actually know for certain what it is, we've just worked it out from experiments.

As an aside, the arrow-looking formation (top left) is for anti-submarine combat only. If you're trying to fight a land base, you should be using the bottom right formation instead.
