Calories card missing from health app on iOS 9.3

Hello all

i have been using the Health app on my iPhone since bit came out and when more apps had updated their apps to work with Helath app i have added more cards to the dashboard

the weird thing that i saw a couple of days ago was that my "Calories" tab is missing from my dashboard !

io mean i still have other tabs like "carbohydrates" "protein" "Heart rate" etc

but calories is missing

so i tried to go to Health data and try to find it but its not there!

is anyone else having the same problem? it seems that calories isn't on data that health app is fetching from other apps any more?
