Garmin Instinct inaccurate calorie masurement

Hello! 

I am a new user of Garmin Instinct Tactical, previously I had Vivoactive HR and it was pretty good measuring calories burned during activities, running distance, etc. 

It's not the most important feature, but I noticed Total daily calories burned (Active) on the watch do not include the ones from sport activities. Is that true or I should check somewhere in the settings and adjust it? 

Also, the amount of calculated calories burned during the day as active is ridiculously small - I am moving most of the time and have 11k steps + every day and it shows me 100 burned calories? (bodyweight/ height/ activity lvl - set the same as before) 

I was wondering if there is any way to adjust that?

Thank you in advance for all your advices and help!


Cheers!
