Question on transferring from Gen 8 to Gen 9

[Bladion]

Hello, all! Since HOME compatibility will not live until next year, I wanted to figure out a way to transfer a Pokemon from my Pokemon Go account to Scarlet/Violet. I transferred a Pokemon from PoGo to HOME and then from HOME to BDSP. But when I try to either save the Pokemon from the BDSP save file, it doesn't allow me to save it as a .pk9 file, or if I try to just drag and drop from one save to the other, it gives me a blank square. Can anyone help me figure out how to solve this issue? Thanks!
