Style names are changed after saving DOCX to HTML and saving back

Hi,

When saving a DOCX file to HTML, then save it back for a couple of times, I noticed some of the style names became very weird.

Code:
var doc = new Document(@".\styles.docx");
var htmlSaveOptions = new HtmlSaveOptions();
htmlSaveOptions.CssStyleSheetType = CssStyleSheetType.External;
doc.Save(@".\stylesOut.html", htmlSaveOptions);

        for (int i = 0; i < 5; ++i)
        {
            var docReopen = new Document(@".\stylesOut.html");
            docReopen.Save(@".\stylesOut.html", htmlSaveOptions);
        }
        var docResave = new Document(@".\stylesOut.html");
        docResave.Save(@".\stylesFinal.docx");

I’ve attached the test files and a screenshot for your reference. This issue doesn’t happen if I used Word ‘save as html’ feature, could you please help me check this?
