Unity: ArgumentException: Getting control 1's position in a group with only 1 controls when doing repaint Aborting

Начал разбираться с кастомным интерфейсом свойств инспектора, так как стандартный перестал устраивать и написал свой кастомный PropertyDrawer, всё хорошо до первого Play, после нажатия на него ловлю ошибку:

ArgumentException: Getting control 1's position in a group with only 1 controls when doing repaint

И пропадает мой кастомный PropertyDrawer с инспектора и не появляется до тех пор, пока не сохраню класс с пустым OnGUI и заново не вставлю код с моим OnGUI

HealthDrawer.cs

#if UNITY_EDITOR
using UnityEngine;
using UnityEditor;

namespace Source
{
    [CustomPropertyDrawer(typeof(Health))]
    public class HealthDrawer : PropertyDrawer
    {
        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            SerializedProperty currentHealth = property.FindPropertyRelative("m_currentHealth");
            SerializedProperty maxHealth = property.FindPropertyRelative("m_maxHealth");
            SerializedProperty minHealth = property.FindPropertyRelative("m_minHealth");

            EditorGUILayout.BeginHorizontal();
            {
                EditorGUILayout.PrefixLabel(label);
                GUILayout.Label("Current: ");
                currentHealth.floatValue = EditorGUILayout.Slider(currentHealth.floatValue, minHealth.floatValue, maxHealth.floatValue);
            }
            EditorGUILayout.EndHorizontal();

            EditorGUILayout.BeginHorizontal();
            {
                EditorGUILayout.PrefixLabel(" ");
                GUILayout.Label("Min: ");
                minHealth.floatValue = EditorGUILayout.FloatField(minHealth.floatValue);
                GUILayout.Label("Max: ");
                maxHealth.floatValue = EditorGUILayout.FloatField(maxHealth.floatValue);
                currentHealth.floatValue = Mathf.Clamp(currentHealth.floatValue, minHealth.floatValue, maxHealth.floatValue);
            }
            EditorGUILayout.EndHorizontal();
        }
    }
}
