Данные времени проектирования WPF не привязаны к изображению

Question

Как и в заголовке.

Дело в том, что изображение правильно связывается во время выполнения, а все остальные свойства связываются правильно во время разработки. Более того, я успешно связал изображения во время разработки в других пользовательских элементах управления \ Pages.
Я уже потратил на это бесчисленные часы, поэтому решил опубликовать здесь вопрос.

Вот мои проблемы c XAML:

Мой конвертер изображений (хотя это не должно быть проблемой, потому что он делает свою работу везде):

using System.Windows.Media;
using System.Windows.Media.Imaging;

    public class ImageSourceConverter : ValueConverterBase<ImageSourceConverter>
    {
        public override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            BitmapImage result;

            if (targetType == typeof(ImageSource))
            {
                if (value is string)
                {
                    string str = (string)value;

                    return new BitmapImage(new Uri(str, UriKind.RelativeOrAbsolute));
                }
                else if (value is Uri)
                {
                    Uri uri = (Uri)value;

                    return new BitmapImage(uri);

Мои пути:

Во время выполнения (изображение, о котором я говорю, слева от большого заголовка «Модель с видом на магазин»):

Во время разработки (обратите внимание на пустой квадрат слева от большого заголовка «Store Design Model», изображение должно быть там):
