Upgraded to a Charge 3: Giving me way too many calories

Hi, everyone!  Thanks to my fitbit, in 2014-2015 I lost 50 pounds.  I later upgraded to an Alta, and after that, to a Charge HR.  I never had any problems with any of them.

 

Recently I bought a Charge 3.  I am currently on some medication that helped me gain 30 pounds, and I'm trying to get it back off.

 

Before, about 10k steps a day would add 400 calories over to MFP.  This was perfectly accurate, I lost weight when I followed it, etc.  

 

But my Charge 3 is wonky.  Yesterday I had 6k steps and it told me I burned an extra 700 calories.  There's no way I'm burning 2600 calories a day with just the steps I get doing my (desk) job and cooking dinner and whatever else around the house.  

 

I thought it was because my heart rate is high due to my meds, so I adjusted my heart rate zones so I had to get up to 110 for it to put me in "Fat burn", but even yesterday with only 40 minutes in "fat burn" instead of the nearly three hours it claimed I was in on Monday, it gave me almost 700 extra calories.

 

I don't know what to do.  I could turn off the HRM but it seems kind of silly to have bought this new device when I could just go back to my Alta or my Charge HR.  My height, weight and age are set correctly.

 

Any advice? Right now I'm at less than 2k steps and it's already given me 130 extra calories.

My versa 2 and inspire hr calculate 1 calorie extra (above bmr) every 8-11 steps. Atvmy height/weight it should be nearly 20steps/calorie. 

 

Changing heart rate zone won't  make a big impact on calories lost walking, but makes a huge impact on high intensity excercises. I changed my HR max to 220, it made every 11-13 steps burn a calorie, but calories burned doing cardio became less than half. 

 

I don't want to disable the HRM so.

I plug my numbers into a spread sheet to get reasonable numbers.
