Opposite Clamps that work. An Sense Mystery

Take a look at the photo. Installed with clamp labels in the same direction, one leg shows negative Watts. Installed with labels in opposite directions, both legs have positive Watts.

Which one is right and are the directions wrong?.. Or am I wrong?

Details: No Solar, 150A Service, Backup generator feeding panel.

Positive on both makes the most sense. FYI - Sense setup process can adjust for opposite-orientation clamps. But if you are unsure, contact support@sense.com.
