Honestly, I feel like that is far too large a deficit for you to be losing at your weight. If you were much heavier, yeah, a 750 calorie deficit (a pound and a half a week loss) is doable, but you simply don't have enough fat to lose that much that fast. You have about 13 lbs to go, which means you're looking at a 1/4 to 1/2 pounds loss per week goal. And 1/2 pound is going to be pushing it.
You need to shrink that deficit by a lot. I would be going for around 250 calorie deficits per day (leaning towards 250), which would mean eating more, and likely burning less.
I really don't know if I trust their BMR calculations for daily burn, either; how tall are you? How much exercise are you doing?
