show us your movement_targets.gd file (paste in the code you have)
YOu should have these properties exported in there

When you have these properties in the script, save script, change to something else in editor to reload it and change back to the .tress file, they should be there.,
Note: in 4.3 godot dont like to have Array[Node2D] or whatever. Just leave it as array
extends Resource
class_name SomeRes
@export var lol_meg_giga_chad: Array
@export var melon_musk: Array
