Apple watch series 7 not tracking calories

Hello! My apple watch is not tracking any of my calories. I have been trying multiple different workouts and it does not say that I am burning any calories. My old apple watch was able to track calories but this one does not. Below I attached some screenshots of my workouts. The first screenshot is of a walk I took on my old apple watch right before getting the new one, and all the others are of the workouts I have had since getting the series 7.
