Golang Google Admin Directory API-无法将ChangePasswordAtNextLogin设置为false

Question

I'm trying to use Go and the Google Admin Directory API to manage some Gsuite user attributes, specifically passwords and changePasswordAtNextLogin. I can build my user and send it to update

srv := client()
user := admin.User{
    ChangePasswordAtNextLogin: forceReset,
    HashFunction:              "MD5",
    Password:                  fmt.Sprintf("%x", md5.Sum([]byte(newPassword))),
}

_, err := srv.Users.Update(email, &user).Do()

and the password will be updated successfully. If forceRest is true then it will set the flag for the user, but if it's false it won't remove the flag! Is this a bug in the Go API library, or am I doing something wrong?

I tried adding ForceSendFields: []string{"ChangePasswordAtNextLogin"} to the User struct and that didn't help.
