How to generate BIP85 Child Key using Bitcoin Explorer?

I've playing with 2 tools:

• Mnemonic Code Converter (site)


• Bitcoin Explorer (CLI) - bx command

For the purpose of test I've used these tree BIP39 mnemonic words: client mixed great.

Using a site I've created successfully BIP32 Root Key using above words which matches bx output:

$ echo client mixed great | bx mnemonic-to-seed | bx hd-new

However when I'm trying to create a matching BIP85 Child Key (in Xprv format), it doesn't match:

$ echo client mixed great | bx mnemonic-to-seed | bx hd-new | bx hd-private -i 0

$ echo client mixed great | bx mnemonic-to-seed | bx hd-new | bx hd-private -i 0 -d # a hardened key

as the site reports the following key (in Show BIP85 section, app format: Xprv, index: 0):

What I am missing?
