Hello Seankudusi,
Generally the Enhancement tab may be replaced by proprietary options of the card manufacturer driver as the settings will overlap. For instance, in the case of Realtek chipsets, the Enhancements tab will be replaced with an Effects tab, that will cover similar settings.
Additionally, it would help if you could provide a specific screenshot with the previous and after to see exactly the options appearing and then missing to help the community to understand you issue in detail.
