It might be coincidence or it might be just the differences in the dynamics of the hive. Hard to actually have true "twin sisters" hives. They may have started at the same time, sit next to each other and have the same type and number of boxes, but they are their own unique organism.
Off topic: Years back, I worked for an architect with twin daughters and had them in a classes I taught at a local private elementary school and they were as different as night and day. So it is with your hives.
Is this hive actually troubled or just not behaving as expected? There is still plenty of time for the bees to cap the honey for winter or for your harvest. Welcome to "bee time."
