Gen 5 BW events showing origin game as BW2 when imported?

[PLAFiles]

Not sure if this is normal, but I downloaded a couple of the BW1 event Pokemon from here (ex: Movie 2011 Victini and a Mewtwo): https://projectpokemon.org/home/files/category/27-english/

But when I put them into PKHeX on my B/W2 sav file, it is saying origin game as B/W2. Shouldn't the origin stay B/W1?

The origin games aren't hard-coded into the wondercard as they were for gen 4 wondercards. This is similar to how gen 6/7 wondercards work as well. In order to generate them correctly, you'll need to drop them in the correct game save file or else the origin game will be randomized between games in the same generation.
