Unable to decrease float stepper

[javydreamercsw]

I have Steppers in a table as follow:

Table options = new Table();
        options.addContainerProperty(Tool.translate("general.name"),
                String.class, null);
        options.addContainerProperty(Tool.translate("level.name"),
                FloatStepper.class, null);
       ...
                FloatStepper stepper = new FloatStepper();
                stepper.setManualInputAllowed(false);
                stepper.setMinValue(0F);
                stepper.setStepAmount(0.5F);
                stepper.setMouseWheelEnabled(false);
                stepper.setImmediate(true);
                stepper.addValueChangeListener(listener -> {
                });
                options.addItem(new Object[]{Tool.translate(skill.getName()),
                    stepper}, skill.getName());
     ...

They display well but don't behave as expected:

• Steps are in 1.0F increments instead of the 0.5F configured.
• The down arrow doesn't decrease the stepper.

I figured out what was the issue. Once I added:
stepper.setNumberOfDecimals(1);
it started working. Still the code should handle it better instead of stopping working without errors and/or output.
