The ranges are all mid-range.
Say you have a 1200-1550 calorie range. If you ate at the bottom of all of your macronutrient ranges, you would probably eat around 900-1000 calories. If you ate at the top of all three macronutrient ranges, you would probably eat 1800-1900.
You're supposed to be kind of mid-rangeish. Or up on one one day, and up on another another day.
Is it likely that this is all it is? You're within the max of all three macros but only just, and that's why calories blows out?
