Hello,
I am using the latest Aspose.Words release 10.5.0. I took an existing Word document with highlighted text and saved it using DocumentObject.Save(MemoryStreamObject, Aspose.Words.SaveFormat.Docx) and DocumentObject.Save("FilePath.docx",Aspose.Words.SaveFormat.Docx).
Both ways gave me the same result. If I open the saved file; select the highlighted text and choose "No Color" from the Highlighter Dropdown in Word; Nothing happens leaving the text Yellow. If I choose another color like Red or Green, the color of the highlight changes.
I have attached the before and after documents.
Thanks,
Bryan
