@GopinathAluri  as the issue is expected behavior in Pega product design there will have been no change in functionality.

See an example message about when localization is possible in Specifying a data source directly in a property , Localization limitations and Localizing controls that rely on Data Pages

The listed Enhancement Requests are still open.  Please liaise with your AE if you need further information:

@BilalA08 Multiselect and Autocomplete are Text Input type of controls, where user will input the content for search and same value will be submitted to the server. Simple Dropdown is a different as user can only select the option from the values where we have option of display value and actual value (there won' be search by entering the value), the underlying actual value will only be submitted to the server.One option is Application can have a custom logic in the data retrieving process by storing the localized values and actual values map.
