[Bug] Unable to get Info while using multiple ImportDocumentAsync

[YourHat]

Context / Scenario

below is the code to initiate local GPT with RAG

        OllamaConfig ollamaConfig = new OllamaConfig()
        {
            TextModel = new OllamaModelConfig("mistral:latest") { MaxTokenTotal = 125000, Seed = 42, TopK = 6 },
            EmbeddingModel = new OllamaModelConfig("nomic-embed-text:latest") { MaxTokenTotal = 2048 },
            Endpoint = "http://localhost:11434/"
        };
        var memoryBuilder = new KernelMemoryBuilder()
            .WithOllamaTextGeneration(ollamaConfig)
            .WithOllamaTextEmbeddingGeneration(ollamaConfig);

        memory = memoryBuilder.Build();

        var desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        var folderPath = System.IO.Path.Combine(desktopPath, "RAGDOC");
        if (Directory.Exists(folderPath))
        {
            var textFiles = Directory.GetFiles(folderPath, "*.json");

            var importTasks = textFiles.Select(async filePath =>
            {
                try
                {
                    await memory.ImportDocumentAsync(filePath);
                }
                catch (Exception ex)
                {
                    Console.Error.WriteLine($"Error importing {filePath} : {ex.Message}");
                }
            } );
            await Task.WhenAll( importTasks );
        }

below is a template for Json files imported

{ "title": "App Name", "sections": [ { "name": "Installation", "chunks": [ {"subSection": "Step-by-Step Guide", "content": "Detailed installation instructions for installation: Step 1, Step 2, etc.", "tags": ["App", "installation", "setup"]} ] }, { "name": "Change Password", "chunks": [ {"subSection": "Procedure", "content": "Detailed steps on how to change your App password.", "tags": ["App", "change password", "procedure"]} ] } ] }

What happened?

let's say that I have "A.json", "B.json", and "C.json". If A and B or B and C are in the RAGDOC folder, I can get information from the files. But, if all A, B, and C are in the RAGDOC folder, I cannot get any information.

Importance

I cannot use Kernel Memory
