I've been trying to complete the BDSP pokedex in Pokemon HOME by using SWSH and PLA sysbots to make BDSP origin mons (I don't own a copy of BDSP). But whenever I transfer the pokemon over to HOME, the app marks it as illegal. Its pokeball doesn't appear next to its name on the summary page like it should. PKHeX says that the pokemon file is legal however, so I'm wondering what I'm doing wrong. I think it might have something to do with HOME not recognizing the pokemon's HOME tracker, since it technically hasn't been transfered into HOME until now. Not sure what the solution to this would be, or if I'm even on the right track.
TLDR, is there a way to create pokemon that originated from BDSP while using a SWSH or PLA save/sysbot without HOME flagging them as illegal?
