BT Variables do not save data

[Ramarolo]

Hi, I have a problem that does not allow me to iterate with the proper flow: some variables created in the BT Inspector are never saved, and I have to manually introduce their value every time I stop Runtime. Photo

I have to click their right arrow every single time I exit from Runtime to introduce their values. They all refer to a component of an object in the Scene. How can I save their values forever?
Thanks

*I add that Reset Values On Restart is disabled in the Behavior Tree component of the character. Photo

External trees are not able to save scene references since they are stored in the project and not the scene. This page explains more:

Referencing Scene Objects - Opsive

As you are creating your tree it is common practice to reference objects within the scene from a Shared Variable or task. For example, in . . .

Thanks for the quick response!
The link of referencing scene objects is very clear. Between the two solutions exposed, I chose the custom script in the character who needs the references of others, as I think it has a better performance calling it once, instead of Find node in each tree iteration.
I shared my script with the 3 references to help future others needing it:

using UnityEngine;
using BehaviorDesigner.Runtime;

public class Reference : MonoBehaviour
{
GameObject player;
Transform playerTransform;
Vector3 playerPosition;

public void Awake()
{
player = GameObject.FindGameObjectWithTag("Player");
playerTransform = player.transform;
playerPosition = transform.position;
var behaviorTree = GetComponent<BehaviorTree>();

behaviorTree.SetVariableValue("Target", player);
behaviorTree.SetVariableValue("TargetTransform", playerTransform);
behaviorTree.SetVariableValue("TargetPosition", playerPosition);
}
}
