ssh-ed25519 fingerprint is invalid (in HostKeyEventArgs) with older servers

Fantastic library, amazingly easy to use - thank you!. The library version 2020.0.1 seems to fail to provide a correct fingerprint (MD5) for e.HostKeyName that equals to "ssh-ed25519". The HostKeyEventArgs (e.Fingerprint) contains 16 bytes that absolutely don't match OS X ssh (nor Windows 10 built-in ssh command output.) I even made sure to execute the command like below to ensure I am requesting the "ssh-ed25519" (to match what's reported by e.HostKeyName).

The ssh command: ssh admin@host-address -o HostKeyAlgorithms=ssh-ed25519 -o FingerprintHash=md5

Please help! The library works correctly with e.HostKeyName of "ssh-rsa", but "ssh.net" doesn't pick "rsa" when connecting to AWS Ubuntu hosts in 2021.

How to reproduce:

1. Connect to an AWS Linux host (Debian versions as recent as 2017),
2. The e.HostKeyName will be "ssh-ed25519"
3. The e.Fingerprint will "not" match the "ssh" command executed manually.

Start at the HostKeyEventArgs entry point and inspect how e.Fingerprint is produced for the ssh-ed25519 host key. Reproduce against an AWS Linux host using the stated ssh command with FingerprintHash=md5, then compare the library's 16-byte fingerprint with the OS outputs. Done means the ssh-ed25519 fingerprint matches the command-line result while ssh-rsa behavior remains correct.
