Component Visibility Issue After Constellation UIGallery Upgrade

[Unnikrishnan_T_N (Unnikrishnan Thunduparampil Narayanapillai)]

Post upgrade to Pega Platform Infinity 25, we upgraded the ConstellationUIGallery version from 3.0.8 to 4.0.3 (latest available version).

After the upgrade, we noticed that a few custom components/widgets that were previously available for selection in Landing Pages are no longer visible in the widget/component selection list in App Studio.

These components were working correctly before the upgrade .

Has anyone faced a similar issue after upgrading to Infinity 25 or UIGallery 4.0.3?
Are there any additional steps required for component registration, AppStatic synchronization, or compatibility updates for custom components in Landing Pages?

Before Gallery Upgrade :

After the gallery update with Pega upgraded to 25.1 :

Example : Banner , Case Launcher

below is a comparison of Gallery 3.0.8 in 24.2 and Gallery 4.0.3 in 25.1

We were specifically using the components highlighted in color earlier, but those items are now missing after the upgrade.

Appreciate your help and suggestions on this issue.

@Unnikrishnan_T_N In library mode you need to add the components to the application to be able to use them. You do this in the reuse library found in App Studio.
