Sample code
_children = new Lazy(() =>
{
var cList = new List();
AsposeVisio.PageCollection pages = _document.Pages;
foreach (AsposeVisio.Page page in pages)
{
foreach (AsposeVisio.Shape shape in page.Shapes)
{
var attachmentData = shape.ForeignData;
if (attachmentData.ObjectData != null)
{
Stream str = new MemoryStream(shape.ForeignData.ObjectData);
var fileFormatInfo = AsposeVisio.FileFormatUtil.DetectFileFormat(str);

                    if (fileFormatInfo.FileFormatType == AsposeVisio.FileFormatType.Unknown)
                        cList.Add(new VisioAttachment(shape.ID.ToString(), $"{shape.ID}{Path.GetExtension(attachmentData.ObjectSourceFullName)}", shape));
                    else
                        cList.Add(new VisioAttachment(shape.ID.ToString(), $"{shape.ID}.{fileFormatInfo.FileFormatType}", shape));
                }
            }
        }
        return cList;
    });

We are sorry we could not find the issue you describe with the file attached.
All objectdata have values.
Sample code:
Diagram diagram = new Diagram(“Less Attachment found.vsd”);
byte[] data = diagram.Pages[0].Shapes.GetShapeIncludingChild(38).ForeignData.ObjectData;
// Three ole object with id 38,39,40 all have values
Console.WriteLine(data.Length);

Please provide a simple project that can reproduce the issue.
Thanks.
