I don't use the FitDay 2.0, so maybe someone else can help you out with the "goal" and "current" numbers, but I will say that to go from 148 to 130 in about 8 weeks puts you at losing over 2 pounds per week, which may be why your calories appear to be so restricted.
FitDay only does the math calculation, no matter how much sense it makes. It doesn't guarantee that it's safe or makes sense; it's purely based on how much you tell it you want to lose and how long you tell it you want it to take.
To lose more than two pounds a week, you would have to be a calorie deficit of greater than 1000 calories per day. That's hard to do when you're only burning 1600-1800 to begin with.
If you move your goal date out a bit, you will probably see a more reasonable number of calories you can eat.
