Why the speak recognition score is 0

I use cognitive speech sdk sample to create a Speaker Recognition profiler, it works fine, the result score is 0.8, then I want to reuse the profile, but the score is always 0. Where am I wrong?

void TextIndependentVerification(shared_ptr<VoiceProfileClient> client, shared_ptr<SpeakerRecognizer> recognizer)
{
    std::cout << "Text Independent Verification:\n\n";
    
    auto profile = VoiceProfile::FromId("3b32c3dc-a974-497f-b6af-7cda3b607751");

    std::cout << "Created profile ID: " << profile->GetId() << "\n";

    SpeakerVerify(profile, recognizer);
 
}
