Extraction of coordinates

I am deploying my model on my Mac using C++. After doing all the processes why only 11 parameters are showing as output? I have used a dataset that contains approx 1000 images. I have labeled the images using a bounding box. Each T-shirt image has 12 labeled points ( 2 HSP, 2 LSP, 4AP, 2 UP, 2WP). Why it is showing like this please help me out.

how can I extract the coordinates of the different points from the bounding boxes in the output of the model? how can I calculate the center point of each bounding box?
