SessionSettings are empty

我正在写一个局域网联机的Demo，我使用CreateSession来创建一个Session并传入我需要的SessionSettings，但是当我从另一台计算机查找Session时，另一台设备确实找到了一个Session，但是其中的数据完全没有初始化，我的代码如下。

FOnlineSessionSettings SessionSettings = FOnlineSessionSettings();
		if(!Params.bUseLAN)
		{
			SessionSettings.bIsLANMatch = IOnlineSubsystem::Get()->GetSubsystemName() == "NULL" ? true : false;
		}
		else
		{
			SessionSettings.bIsLANMatch = true;
		}
		SessionSettings.NumPublicConnections = Params.NumPublicConnections;
		SessionSettings.bAllowJoinInProgress = true;
		SessionSettings.bAllowJoinViaPresence = true;
		SessionSettings.bShouldAdvertise = true;
		SessionSettings.bUsesPresence = true;
		SessionSettings.Settings = Params.Settings;
		SessionSettings.BuildUniqueId = 1;
		SessionSettings.bUseLobbiesIfAvailable = true;

		const ULocalPlayer* LocalPlayer = GetWorld()->GetFirstLocalPlayerFromController();
		if (!OnlineSessionInterface->CreateSession(*LocalPlayer->GetPreferredUniqueNetId(), NAME_GameSession, SessionSettings))
		{
			MultiplayerOnCreateSessionComplete.Broadcast(false);
			OnlineSessionInterface->ClearOnCreateSessionCompleteDelegate_Handle(CreateSessionCompleteDelegateHandle);
		}
//下面是查找Session的部分
sessionSearch = MakeShareable(new FOnlineSessionSearch);
	sessionSearch->MaxSearchResults = MaxSearchResults;
	if(Params.bUseLAN)
	{
		sessionSearch->bIsLanQuery = true;
	}
	else
	{
		sessionSearch->bIsLanQuery = IOnlineSubsystem::Get()->GetSubsystemName() == "NULL" ? true : false;
	}
	sessionSearch->QuerySettings = Params.Settings;
	sessionSearch->QuerySettings.Set(SEARCH_PRESENCE, true, EOnlineComparisonOp::Equals);

	const ULocalPlayer* localPlayer = GetWorld()->GetFirstLocalPlayerFromController();
	if (!OnlineSessionInterface->FindSessions(*localPlayer->GetPreferredUniqueNetId(), sessionSearch.ToSharedRef()))
	{
		MultiplayerOnFindSessionsComplete.Broadcast(TArray<FOnlineSessionSearchResult>{}, false);
		OnlineSessionInterface->ClearOnFindSessionsCompleteDelegate_Handle(FindSessionsCompleteDelegateHandle);
		MultiplayerLog.Broadcast(TEXT("Find sessions failed with unknown error!"));
	}

我感到非常困惑，我想知道这是什么原因导致的
