Good morning,
I'm new here, and new in the crypto world.

Earlier this year I opened an account with Kraken and bought some Bitcoins and some Etherums.
A few months ago I also bought a Ledger key (with $20 offered in bitcoin)

Since I made a first transfer of Bitcoins (for test) from my Kraken account to "Ledger Live"

Transfer n°1: 100€, Kraken Fee: 0.00020 BTC (about 5€), Arrived on "Ledger Live" Fee: 0.00019023 BTC (4,708€)
blockstream.info: SEGWIT FEE SAVINGS This transaction saved 27% on fees by upgrading to native SegWit-Bech32

Transfer n°2: 1900€, Kraken Fee: 0.00020 BTC (about 5€), Arrived on "Ledger Live" Fee: 0.00038385 BTC (9.282€)
blockstream.info: SEGWIT FEE SAVINGS This transaction saved 17% on fees by upgrading to native SegWit-Bech32

I claim my $20 of Bitcoin Offer: Arrived on "Ledger Live" €18.05 Fee: 0.00021581 BTC (€5.23)
blockstream.info: SEGWIT FEE SAVINGS This transaction saved 5% on fees by upgrading to native SegWit-Bech32

Do all these Fees seem normal for you?
But above all, why in Transaction n°2 I paid quazi double 0.00038385 BTC instead of 0.00020 BTC? (I have a screenshot that shows 0.00020 BTC of Fee before clicking on send in Kraken)

Should I contact Kraken, or there are other Fees added "after Kraken" in the transaction process ?

I don't understand.
Thank you.
