Initially, when loading a save, there will only be one variables. To understand which variables need to be changed, first upload the System.json file to the site, and then save. (File in the data folder.)
In addition to the save itself, you need the global.rpgsave file, if you don't have it, then do the following. Move your saves from the Save folder, then go to the game and save. Then put the saves back with confirmation of replacing the new ones. Then load this slot and save it. Now your saves are visible.
