Azure Custom Vision Probability Threshold Keeps Resetting to 50%

Hi everyone,

I've done some General A1 training on some image object detection models but I need the Probability Threshold to stay at 90% in order to keep the accuracy high, but every time I leave the project and then go back into it, it resets to 50%.

How can this be fixed so it remains at 90%, even after I leave the project?
Thanks in advance.

    @Chris Buley Thanks for the question. Those are default values for the Probability Threshold slider on the left pane of the Performance tab. This is the level of confidence that a prediction needs to have in order to be considered correct (for the purposes of calculating precision and recall).

    We are able to retain at 90% after leaving and coming back to the project as shown below.
