@thiru1711 This is not a bug and replacement works properly. The issue occurs because & character is used by Aspose.Words for escaping metacharacters, like line break or page break. Please see our documentation for more information:
https://reference.aspose.com/words/net/aspose.words/range/replace/
So to get the desired result you should escape & character with another & character:

table2.Range.Replace("&&lowst0", "0", opts1);

To remove highlight color you can use FindReplaceOptions.ApplyFont. For example see the following code:

FindReplaceOptions opts1 = new FindReplaceOptions();
opts1.ApplyFont.HighlightColor = Color.Empty;

table2.Range.Replace("&&lowst0", "0", opts1);
table2.Range.Replace("&&lowet20", "20", opts1);
table2.Range.Replace("&&midst40", "40", opts1);
table2.Range.Replace("&&midet60", "60", opts1);
table2.Range.Replace("&&d1", "1", opts1);
table2.Range.Replace("&&highst80", "800", opts1);
table2.Range.Replace("&&ac", "123", opts1);
