"I can't find every address, some coins missing!"
When you send coins out, an address usually has to be emptied completely. Most wallets send the "change" back to a different address inside your wallet. On the Derivation Path section of the BIP39 file, change the "External / Internal" value from "0" to "1" to list the "change" addresses. Then find the address that has the rest of your coins.
