Rasberry Pi and positions of items reported wrong

Hi,
I’ve set up a number of Raspberry Pi 4 with DeepStack as per the instructions:

https://python.deepstack.cc/raspberry-pi

but I’m finding that although it if finding items OK it is reporting them in the wrong positions. If the item is at the top of the image it showing it below and if its at the top its showing it above. The left and right seem OK.

Is this a bug in the Pi DeepStack?

I’m using the AITool software program https://ipcamtalk.com/threads/tool-tutorial-free-ai-person-detection-for-blue-iris.37330/https://python.deepstack.cc/raspberry-pi

If I use DeepStack on a normal W10 desktop with docker the positions are fine.
