YOLOv11 ONNX Export Error with Batch > 1 and NMS

Environment:
Ubuntu 22.04
Python 3.10.12
Ultralytics 8.3.155

Executing:

yolo export format='onnx' dynamic=True model=yolo11n.pt nms=True
yolo predict task=segment source=images batch=4 model=yolo11n.onnx

Expected Behavior:
4 segmented Images

Actual Behavior:
Only the first Image is segmented. The other 3 images have 0 detections / segmentations. This is also occurring in my own tensort inferencing routines.

If I export without nms, then the same predict cli command will segment all 4 images.
