Step 6

I see x1, x2, x3 priv key in the wallet file but when i copy e.g X1 to create new wallet, electrum doesn't show "next" button like i would write the wrong xpriv key.

What am I doing wrong here? I need to create wallet_1 with xprv key X1 and wallet_2 with xprv key X2 right? The X3 xprv key says "null" - assuming this means i got disabled 2FA right?
