4 Unconfirmed transactions ( more than 30 days now ) - Help needed :-[

[bob123]

Since the address type is correct, i can only think of the options mentioned by HCP:
1) Multiple "accounts" used -> derivation path needs to be adjusted or 2) BIP39 passphrase has been used.

Another option might be that you imported the wrong mnemonic code.
How sure are you that this mnemonic codes belongs to the hardware wallet? Do you see any incoming/outgoing transactions in electurm? Is your wallet fully synced?
