Error: fundamental matrix size overgrowing to 3x9

edit

I am trying to find the fundamental matrix by manually identifying 7 corresponding points in two images and using the findFundamentalMatrix function. However on printing the matrix, it turns out to be 3x9. Seems to be a bug in my code but I cant figure it out.

void mouseEventOne(int event, int x, int y, int, void* param){
 //select points in first image. store in one.
    }

void mouseEventTwo(int event, int x, int y, int, void* param) {
//select points in second image. store in two.
  set flag after 7 points
}

int main(int argc, char** argv) {

setMouseCallback("ImageOne", mouseEventOne, (void *) &ptOne);
setMouseCallback("ImageTwo", mouseEventTwo, (void *) &ptTwo);

for(;;) {

    if(one.size() == 7 && two.size() == 7 && flag){
        F = findFundamentalMat(one, two, CV_FM_7POINT);
        flag = false;
        cout<<F<<endl;
     }

    imshow("ImageOne", imageOne);
    imshow("ImageTwo", imageTwo);

    char s = (char)waitKey(30);
    switch(s){
        case 'q':
            return 0;
    }
}

Example of F that I get:
