IntelliJ / Spring: Properties hint wrong and no recommendations

given following properties:

// TestProperties.class
@Configuration
@ConfigurationProperties(prefix = "test.props")
public class TestProperties {

    protected OrderProperties order = new OrderProperties();

    public OrderProperties getOrder() {
        return order;
    }

    public void setOrder(OrderProperties order) {
        this.order = order;
    }
}

with

// OrderProperties.class
public class OrderProperties {
    protected OrderMode mode;

    public OrderProperties() {
        this.mode = OrderMode.DISABLED;
    }

    public OrderMode getMode() {
        return this.mode;
    }

    public void setMode(OrderMode mode) {
        this.mode = mode;
    }
}

and

// OrderMode.class
public enum OrderMode {
    DISABLED,
    ENABLED;

    OrderMode() {
    }
}

then intellij says the not correct property would be correct (no hint):

and the correct property would be incorrect (hint)

And i also dont get any auto suggestions for the property like “disabled” or “enabled” but OrderMode is an enum
