This issue is caused by setting MinProps > MaxProps.
This is further exacerbated by the UI not properly setting the MinProps/MaxProps in the cfg.json from the slider.
The work-around is to turn on/off BalancedPropCount, then change min/maxprops, Save and verify the change makes it to the cfg.json, or just edit the cfg.json manually.
