Time in Heart Rate Zone not showing in Exercise

[keen153]

I have a Google Pixel Watch and the first week exercise calculated and showed the Heart Rate Zones properly. 

After that and ever since, the zones aren't calculated.

 

If you go into the exercise, it clearly shows that I'm hitting the different zones and my heart rate is calculating. The graph shows the different zones but it still says zero minutes in "peak, cardio, and fat burn" zone above. 

 

Please help.

@keen153 this issue has been reported multiple times here by Pixel Watch users so you can search the forum but I can't recall any solution to it

I'm also having this issue, I'm hitting Zones but it's reporting 100% below zones 😕
