C# auto-insert data from SQL table to web application

I have a problem with inserting values from a SQL table (pgadmin) to a web application. If I check my table in pgadmin, all is ok:

But if I push it into application on Azure, it returns only:

I don't know where the problem is.

display.data.razor:

@page "/displaydata"
@using WebApplication1.Data;
@using WebApplication1.Services;
@inherits OwningComponentBase<DataService>

<h1>Display data</h1>

<table border="1">
    <tr>
        <th>
            id
        </th>
        <th>
            Nazov IMG
        </th>
        <th>
            label
        </th>
    </tr>

    @foreach (WebApplication1.Data.Dataset item in sc)
    {
        <tr>
            <td>@item.relid</td>
            <td>@item.name</td>
            <td>@item.label</td>
        </tr>
    }

</table>

@code {
    public System.Collections.Generic.IList<Dataset> sc;

    protected override void OnInitialized()
    {
        sc = Service.displaydata();
        foreach (var item in sc)
        {
            Console.Write(@item.relid + " " + @item.label);
        }
}
}

Result of Console.Write(@item.relid + " " + @item.label):

2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)2 "Gold(99.64134)

    public class DataService

        {
            _dbcontext = _db;
        }
        public List<Dataset> displaydata()
        {
            return _dbcontext.results.ToList();
        }
    }
}

Data:
