negative values in output coordinates left_x, top_y, width, height

Hey everyone,
I trained the YOLO network by following all the steps from the link
https://github.com/AlexeyAB/darknet#how-to-train-to-detect-your-custom-objects
What is the meaning of negative values in the output coordinates that we get when we run the command:
darknet.exe detector test cfg/coco.data yolov4.cfg yolov4.weights -ext_output dog.jpg
The predictions on my test images were good and the bounding boxes drawn on the prediction.jpg were correct. But some of the values I got were:
left_x: 74 top_y: -5 width: 92 height: 167
left_x: -1 top_y: 47 width: 35 height: 119
left_x: 248 top_y: -8 width: 77 height: 159
left_x: 336 top_y: -1 width: 60 height: 144
Is my understanding on the coordinates correct?
left_x = top left x coordinate of bounding box
top_y = top left y coordinate of bounding box
width = with of bounding box
height = height of bounding box

Thank you!
