Is your tracker only a stage? It says you have 3kg (about 7lbs) left to lose. With so little to lose, your body only wants to lose that slowly, and you should be aiming for a half a pound a week - only a 250 calorie daily deficit. If you're burning 550 in exercise most days that means eating 300 above your maintenance (non-exercise) level to support that level of exercise and still keep an appropriately small deficit.
So yeah, that value could be right.
If you have been eating lower, you're happy lower, and you're successfully losing weight on lower, then bring your goal date forward. That will make your range lower.
You're right that Spark guesstimates your calories burned based on your time, but also, it's the calories to burn value that is used in calculating your range. So if you're doing triple what that says, you should probably update it.
On the Fitness Goals page is a box to input how many calories you actually do burn per week. That will ensure your intake range is as accurate as possible for your goals. (It may or may not change).

I'd recommend updating your calories burned goal to reflect the amount of exercise you're actually doing. Just click the Fitness Setup button at the top of your tracker, and you can adjust the number from there. It may or may not change your recommended calorie and nutrient ranges.
