YOLO11n - NMS not working correctly - duplicate detections impacting mAP

@shashi - thanks again for looking into it. I’ve uploaded two .pt files, exp_1_yolo11n.pt and exp_1_yolo11n_singlecls.pt, probably not needed but for good measure I’ve added the args yaml for the first (two class) model.

Both of these models were trained using Ultralytics

Thanks again!
