Question on Heart Rate

I have a heart rate monitor that I use at every workout. A few months ago, my HR was in the high 160s-low 180s when I was doing cardio. But last night I was working out and it wasn't going above about 163, and averaged in the high 150s.

To give some background--I use the elliptical, and use either the fat burning (gradually reaches a high intensity and then stays there most of the workout, then gradually goes back down), the interval, or the cross training (longer intervals) settings. My legs are working really hard and I am feeling it in the muscles when I do the cardio, but yet my heart rate is so low. And I've tried doing less resistance and just going faster, but then my HR is between about 150 and 155.

What am I doing wrong? Should I just stay at that heart rate and be happy that I am burning more fat calories, or should I be trying to get back into that higher range to burn more calories overall? I guess I'm just frustrated at how much longer it takes me to burn the same amount of calories now as I did before. Whereas I used to burn about 12 calories a minute, now I'm down to less than 10. Thanks for the help.
