Hello and goodevening, can anyone help me on how to solve this problem? I've been using 2D game and i have a save and load Singleton (BackbuttosaveandLoad.gd), It was all okay, the save game is saved the global_position x and y, but the problem is when i click a continue button which is connected to the load_game is, resetting the position to a default, and it seems like it didnt retrieve the json file in it, here's the code

extends Node2D

const SAVE_PATH = "user://save_json.save"
var current_level = ""

func save_game():
    
    var file = FileAccess.open(SAVE_PATH, FileAccess.WRITE)
    var save_dict = {}
    # Save the spawnpoint value to the dictionary
    save_dict.global_position = {}
    save_dict.global_position.x = global_position.x
    save_dict.global_position.y = global_position.y
    save_dict.current_level = current_level
    
    print("Saved file")
    file.store_line(JSON.stringify(save_dict))
    OS.shell_open(ProjectSettings.globalize_path("user://"))
    file.close()
    pass
func load_game(check_only=true):
    if not FileAccess.file_exists(SAVE_PATH):
        print("FIle not Found")
        return false
    else:
        var file = FileAccess.open(SAVE_PATH, FileAccess.READ)
        var json = JSON.new()
        json.parse(file.get_line())
        var save_dict = json.get_data()
        if typeof(save_dict) != TYPE_DICTIONARY:
        # Return false if the data is not a dictionary
            print("Dictionary Not Found")
            return false
        if not check_only:
            print("restore data??")
            _restore_data(save_dict)
func _restore_data(save_dict):

    global_position.x = save_dict.global_position.x
    global_position.y = save_dict.global_position.y
    current_level = save_dict.current_level
    print("Position: ", position.x, "%", position.y)
    print("Position: ", position)
    print("Current level: ", current_level)
    pass
#

and also in the main_menu.gd, the load_game() that was connected in continue button(continue pressed) is it was always disable the output in it.
