I'm dealing with one SegWit private key on a paper wallet (LM...), not a BIP39 seed.
Creating 3 different wallets in Electrum makes no sense to me, I think you're misunderstanding but thanks for the help.
I agree that it makes no sense, but "this is the way"
You cannot create one wallet with 3 derivation paths in electrum
You need to choose one derivation path for each wallet. If anyone knows a different way to do this in electrum please share.,
