How do I set custom heart rate zone?

[SunsetRunner]

I have been advised by Fitbit customer support to set custom heart rate zone on my versa 2 as it's showing very low calorie burn for all types of workouts (cardio and weights)

I know there's a formula to follow but I can't figure it out.

My resting heart rate is 51 and I'm 44 years old. 

My previous Fitbit (versa lite) had consistent readings during workouts which is why I believe there is an issue with this newly purchased versa 2.

Thank you for any support or advice
