Yeah, green wallet. Not sure. They are a BIP32, but I thought that if you put the master key in another wallet it would find all sub accounts.

The derivation path for Green is m/84'/0'/0' or m/49'/0'/0' and Blue uses m/44'/0'/0' and Nunchuk uses m/84'/0'/0'
So I'm guessing that your using m/49'.... and the other wallets aren't seeing it
I had no idea this mattered. Where do I learn about this?
Unchained has a good article about them https://unchained.com/blog/bitcoin-derivation-paths/
If you have sparrow you can manually enter them when you import a wallet so you can really mess around and look for your account
