Adding yubikey with ykfde and luks asking to decrypt master key before luks prompt during boot

Hi!

So after getting this luks encryption to work with Yubikey using YKFDE, i run in to that during boot it asks me twice for a password.

The first message says:
Attempting to decrypt master key…
Enter passphrase for hd0,gpt2 (…):

This is something new, earlier it has only been the luks prompt for password, and that one still prompts and asks for password och challenge for the yubikey.

What is this step and is it possible to remove/skip?

The password for the master key is the same as for the luks encryption.
If I change the password for the luks encryption it changes for the master key.
But the luks volume that is encrypted is /dev/nvme0n1p2.
And I also don’t want to keep a “handy” password for the encryption now when I have the YubiKeys.

Thank you!
