Can't delete U2F key

Hi,

I reset one of my yubikey, I renrolled it again here, but I can’t delete the old one.
Got this error : An error occurred: param is missing or the value is empty: second_factor_target

I have 3 keys (4 with the old key) on privacyguides.net. Try to delete TOTP, it works well.
I’m on edge on W11, and on vanadium on android, if that matters?

Thanks
