Where exactly please?
In which field?
Are you sure about that?
Yes. You can enter the master private key at:
https://iancoleman.io/bip39/.
Scroll to BIP32 root key and paste your xpriv there. After that, scroll a bit further to change your derivation path to suit your needs.
Yes you're right it works...
But the adresses are all in legacy format while I have legacy and bech32 adresses in my wallet.
The private keys seem to be the same at least, so how can I display the adresses in the bech32 format please?
Choose BIP141 at the derivation path part, choose P2WPKH.
I'm assuming your wallet isn't using BIP84 since it's generating both? If it doesn't work out for you, try BIP84.
