1. if you changed your calories burned goal by more than 70 cals and your range didn't move up by 10 cals each side, then your goal is too aggressive for the calculator to give you proper ranges. this means you need to push your goal date back and lower your loss per week number.
2. you can't burn 130 cals a day and only have a weekly burn of 700 cals. something in your math is off. 700 cals a week divides out to 100 cals a day.
3. it really depends on your current size and what you are trying to lose. if you are a fairly petite woman, you might need to be fairly close to that 1200 for most of your loss. if you also have a lot to lose [like 100 pounds plus] being near 1200 can maximize your loss while you have a lot to lose. www.sparkpeople.com/resource/calorie_calcu
this is how your ranges are calculated. if you get a number lower than 1200 [as in point one] it will dump you into the lowest ranges instead of telling you that you can't reasonably lose that amount at that rate. but you can do the math yourself and see the why of where you are right now and how those numbers were calculated for your ranges.
