When I use helium/crypto, the Keypair obtained by the fromWord method is not the same as the keypair obtained by helium/ crypto-reacts-native

----gen by helium/crypto(libsodium-wrappers 0.7.13)---- gen privateKey: 1111Pgcc....D69 address b58: HU2uo...63s

----gen by helium/crypto-react-native(sodium 1.0.18)---- fact privateKey: 2JbWe5jN...LoT

Since the mnemonics do not satisfy bip39's rules, I tried to import the wallet into backpack-wallet with my privateKey, but I could not get a matching private key.
