My guess is that your old accounts gave you a calorie range based on your exercise calories burned goal, while your new account is giving you a range based on how much exercise you've tracked. I did look up your account and you have 3 associated with the same email address. If you'd like to use one of the old accounts instead, send me a SparkMail and I can help you log in.
When you manually change the calorie range SP has given you, it doesn't automatically update your nutrient ranges- you have to manually change each of those as well. Are you doing a lot of exercise? The range you've been given does sound a little high based on your weight loss goal.
