ED25519 key not being offered to server

Just as the title says, RDM is not offering ED25519 key upon connection to server and login fails.
sshd[9656]: Unable to negotiate with 1.2.3.4 port 1029: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]

RDM is only offering SSH-RSA and SSH-DSA, but not ED25519. Algorithms has ED25519 enabled and the connection is using defaults. SSH key is saved into credential repository and password for the key is saved as well. Tried loading the key into agent and I can connect with the key using FileZilla to initiate an SFTP connection.
sshd[9999]: Accepted publickey for user from 1.2.3.4 port 13691 ssh2: ED25519 .....


What am I missing to get RDM to use ED25519 when connecting?

Hello,

I will contact our Engineering Department in order to see if that is something that we support in RDM.
I will get back to you as soon as I will have a reply from them.

Best regards,

Hello,

Our Engineering Department just confirmed that we support ED25519. For this reason, could you please make sure that you are not using the "Legacy Terminal" for your SSH Shell connections?

To verify this, please go under File -> Options -> Types -> Terminal and make sure that the option "Use legacy terminal" is unchecked:
