HR Fat Burn Zone incorrect for me

[Colinm39]

Since the changes in the Dashboard Activities I have notice an error in the way my HR is displayed because the colour break outs are incorrect.

At my age, 77 years my minimum Fat burn Zone should start at 71 bpm, 220 - 77 = 143 * 50% for minimum Fat Burn.= 71 rounded.  Not a big deal but while I'm asleep as per the image below.. My RHR is 52 bpm  There is only one peak at over 71bpm....  Lovely if my Fat Burn was over 60% of my sleep time....

An Update...

The readings on the Blaze are correct. The moment the HR goes over 70 it shows "Fat Burn"

I know it's only window dressing but in the image below of my sleeping HR there are only twp peaks over 71bpm, the start of my Fat Burn Zone.  It is correct for the 2 minutes... but not the colours.. The Ionic is correct..

Fat burn zone colours appear to be fixed.. 71bpm is the crossover point for me...
