Hi,

Thanks for your inquiry. In your case, I suggest you please use ListLevel.NumberFormat and ListLevel.NumberStyle properties for your requirement. Please read following documentation link for your kind reference.

https://reference.aspose.com/words/net/aspose.words.lists/listlevel/

Please check the following code snippet to work with List. If you are not using numeric lists in your document, please share your document for investigation purposes.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Aspose.Words.Lists.List list = doc.Lists.Add(ListTemplate.NumberDefault);
list.ListLevels[0].NumberFormat = "1-";
list.ListLevels[0].NumberStyle = NumberStyle.Number;
list.ListLevels[1].NumberFormat = "1.1-";
list.ListLevels[1].NumberStyle = NumberStyle.Number;
list.ListLevels[2].NumberFormat = "1.1.1-";
list.ListLevels[2].NumberStyle = NumberStyle.Number;
// Apply list formatting to the current paragraph.
builder.ListFormat.List = list;
// Exercise the 3 levels we created two times.
for (int n = 0; n < 2; n++)
{
    for (int i = 0; i < 3; i++)
    {
        builder.ListFormat.ListLevelNumber = i;
        builder.Writeln("Level " + i);
    }
}
builder.ListFormat.RemoveNumbers();
builder.Document.Save(MyDir + "AsposeOut.doc");
