Difference between HR Load & Power Load

As you can see from the image I did a workout today and the difference between the estimated HR load and the Actual Load was 12 (78-66) which as a percentage of 78 is 15.4% not 5.1% as shown on the graph. Am I reading this correctly?

Tx for picking this up. I have fixed it and will deploy Tues AM (GMT+2).
