I'm trying to recreate Pokemon from some of my older games that I didn't get through PokeBank before it closed. I want to use them in the newer games and put them through Pokemon Home. I'm currently using PKHeX v2023.09.25 with the Auto-Legality Plugins and it's saying the Pokemon are Legal. I can trade them offline and online but when I try to put them in Pokemon Home I get error code 10015. Other Pokemon I have go through fine but the new mons are always showing this error. I've tried making the caught date before Pokebank closed, I've tried making them in Shield, Brilliant Diamond and Scarlet, I've also tried making them in their respective games (Alpha Sapphire, Heartgold, and Emerald) but I can't seem to find a solution. I have tried to search for a solution but nothing seems to relate to my issue, I'm using the most recent update of the Pokemon games and Pokemon Home v3.1.1 which is also the latest version right now. Any help would be greatly appreciated!

Not sure if you worked it out yet, but the game (and gender) are also used when checking for OT. So even with the Trainer Name, ID, and SID the same; a pokemon from SM will never treat a BDSP trainer as the OT. I think the best way to solve your problem would be to gen the Pokemon you want as eggs in the BDSP sav to have you as the OT, or have them as already hatched but met as an egg.
