Steps to reproduce:

1. Open any Android project.
2. Open 'Build Android APK' from build steps.
3. Click on 'Create Templates' button. 
4. Edit app data, like package name, version code & name, app name, add icons.
5. Save the file.
6. Build the app and run it on the device - check app name and icons.

Expected: Changes should be reflected on the device 

Actual: Changes are not reflected in the app when it's built. The Android Manifest file in the project location looks good, but the one created in the build folder has all the missing changes. 

Reproducibility:  100% 

NOTE: Also when we use a project with existing Android Manifest (e.g. https://doc.qt.io/qt-6/qtcore-platform-androidnotifier-example.html)  - editing it in GUI breast the ability to build the project.
