Length validator only working for default setttings

1. Add the string type in enginio dashboard
2. Add a length validator for the added string type, like:
{
"minimum": 0,
"maximum": 5,
"message": "value is out of bounds"
}
3. Save(click "Add Validator")
4. Wrong description on the validator rule(use default setting instead of the custom one)
5. validator only working in default setting(custom setting saving failed actually)
