Fix Double Category on Enatega Customer Application

Describe the bug
On Enatega Customer app the double category is not working fine. When this module is done by Talha please reuse that code to resolve this issue

The issue names only the Enatega Customer app and the double-category module; no files, tests, or entry points are provided. First locate the customer-app category implementation and compare it with Talha's completed module when available. Done means the double-category behavior works correctly in the customer app, but the expected behavior and test are not specified.
