Next2UAF tool doesn't put artist's name and a lot of song info into json

[SellPL]

As said in the title, it adds this to json:

    "SongDesc": {
        "MapName": "Woof",
        "JDVersion": 0,
        "OriginalJDVersion": 0,
        "Artist": "",
        "DancerName": "",
        "Title": "",
        "Credits": "",
        "NumCoach": 2,
        "MainCoach": 0,
        "Difficulty": 0,
        "SweatDifficulty": 0
    }

this code writes data into the put the codename here.json:

        with open('temp/' + jsonCodename + '.json', "r", encoding='utf-8-sig') as raw:
            jsonMainData = json.load(raw)

but, as you can see, some data is missing. Is there any way to fix this?

Just Dance Next JSONs doesn't have song info besides the MapName, everything else is stored in the SongDB There isn't anything much that I can do about it, i'm sorry.
