Why are there two lists of the same thing in my inspector?

Unity Engine

So this is the waypoints list code:

public List<Transform> waypoints;

and this is my custom inspector code:

using UnityEditor;
namespace Handlers.Pathing_Handler {
    [CustomEditor(typeof(PathingHandler))]
    public class PathingHandlerEditorButtons : Editor {
        // Waypoints Array Reference
        private SerializedProperty _waypoints;
        private void OnEnable() {
            // Waypoints Array Reference Initialization
            _waypoints = serializedObject.FindProperty("waypoints");
        }
        public override void OnInspectorGUI() {
            base.OnInspectorGUI();
            EditorGUILayout.PropertyField(_waypoints);
            serializedObject.ApplyModifiedProperties();
        }
    }
}

and this happens:

and if I open or close one they both open and close:

5804869--613846--upload_2020-5-4_20-28-14.png

So when I try using [HideInInspector] on waypoints like this:

[HideInInspector] public List<Transform> waypoints;

they both vanish from the list just leaving a label named “Waypoints” as seen below:
5804869--613852--upload_2020-5-4_20-31-46.png

So how do I use the Editor class to show the waypoints list only once? I need to do so through the Editor class because I’m doing everything else inspector related there and I want to control the order of everything.

This line draws all the default inspector stuff (including any public fields):

base.OnInspectorGUI();

So that’s where the first Waypoints field is being drawn.
Then your EditorGUILayout.PropertyField(_waypoints) call shows it the second time.

Ohhh that makes a lot of sense, thanks!
