Syncfusion.Pdf.Parsing space problem

        FileStream inputDocument = new FileStream(filePath, FileMode.Open);

        PdfLoadedDocument loadedDocument = null;

        StringBuilder sb = new StringBuilder();

        try

        {

            loadedDocument = new PdfLoadedDocument(inputDocument);

           for (int pageIndex = startPageIndex - 1; pageIndex <= endPageIndex; pageIndex++)

            {

                sb.Append(loadedDocument.Pages[pageIndex].ExtractText(true));

            }

            loadedDocument.Close(true);

        }

        catch (Exception exc)

        {

            this.logger.LogError(exc.Message);

            return string.Empty;

        }


 return sb.ToString();


It puts spaces where there should be no spaces when converting PDF to text. It also connects the places where there should be spaces.

This is the part of pdf:

This is the result text:
