We used following complete code snippet to remove the text from your PDF using Aspose.PDF for .NET 20.9 and did not notice any issue:

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(dataDir + @"HVAVdiagrams_RUS.pdf");
// Used text showing operators
Operator[] operators = new Operator[]
{
 new Aspose.Pdf.Operators.ShowText(),
 new Aspose.Pdf.Operators.SetGlyphsPositionShowText(new List<Aspose.Pdf.Operators.GlyphPosition>()),
 new Aspose.Pdf.Operators.MoveToNextLineShowText(),
 new Aspose.Pdf.Operators.SetSpacingMoveToNextLineShowText(0,0,""),
};

foreach (Page page in pdfDocument.Pages)
{
 List<Aspose.Pdf.Operator> list = new List<Aspose.Pdf.Operator>();
 OperatorCollection pageOperators = page.Contents;

 foreach (Operator op in operators)
 {
  OperatorSelector operatorSelector = new OperatorSelector(op);
  pageOperators.Accept(operatorSelector);
  list.AddRange(operatorSelector.Selected);
 }
 pageOperators.Delete(list);
}
pdfDocument.Save(dataDir + "TextRemoved_operators_20.9.pdf");
