Nested ordered lists in word are not converted to HTML correctly

Hi, I am using Aspose.Words for .NET 21.11.0 to convert Word files to HTML. For nested ordered lists like

1.	Level
1.1.	Level 2
1.2.	Level 2

it SOMETIMES only converts to

1.	Level
1.	Level 2
2.	Level 2

To make it work, aspose uses CSS style tags with counters.
But I do not understand why this sometimes works and sometimes not. Attached 2 files with 2 examples, one is OK, one is not OK.
Any help is appreciated, thanks!

These are the save options I use:

HtmlSaveOptions options = new HtmlSaveOptions();
options.ExportRoundtripInformation = false;
options.UseHighQualityRendering = true;
options.SaveFormat = SaveFormat.Html;
options.PrettyFormat = true;
options.TableWidthOutputMode = HtmlElementSizeOutputMode.All;
options.ExportHeadersFootersMode = ExportHeadersFootersMode.None;
options.ExportImagesAsBase64 = true;
options.ExportListLabels = ExportListLabels.ByHtmlTags;
options.ExportTextInputFormFieldAsText = true;
options.ExportDropDownFormFieldAsText = true;

@jnenning The problem is not reproducible with the latest 24.4 version of Aspose.Words. Here is HTML produced on my side using the latest version:

Please try using the latest version and let us know if the problem still persists on your side.
