Body Fat Percentage

I went to the Bod Pod and learned that I am 25.7% body fat.
Now, that would be okay with me if this was my body fat percentage at the beginning of the year, but I have been working out and taking multiple fitness classes since January and lost 10 pounds. I thought I had something to be proud of and I was hoping desperately to be in the 20-23% range.

At this rate, I don't even want to know how high that body fat percentage was beforehand.
For some more information I am a 19 year old female. 4'11".
The pod measured my fat weight is 25.4 lbs and my lean weight is 73.6.
My total weight is 99 lbs.
I do NOT want to lose weight! I just want to lose the fat weight and up my lean weight.

I just don't know what I am doing wrong. I do at least four days of cardio a week. I am in turbo kick and zumba (cardio based) and I do strength on my own time at least twice a week.
I eat well too, trying to get all my lean fats, proteins, minimal but needed carbs, etc. in.
I feel so bad about myself right now.
Even after I lost 10 lbs, I still don't feel as fit as I should be. Despite going to the gym regularly and eating right. What can I do?
Thanks.
