Reproduction steps:
1. Open the attached project “ReproProject”
2. Select (menu bar: Tools > Build example) to build
3. Check the build type once the building process is finished

Expected result: The build type is “AOSBuild.aab”
Actual result: The build type is “AOSBuild.apk”

Reproducible with: 2020.3.45f1, 2020.3.48f1, 2021.3.33f1, 2022.3.15f1, 2023.2.3f1, 2023.3.0a17
Not reproducible with: 2020.3.44f1

Testing environment: macOS(Intel) 14.0 Sonoma, Windows 10 Pro 22H2

Notes:
- When the Build Settings Window is used to build the App Bundle( Google Play) and the name of the app to be built is saved as “testing.apk” the generated build will have a type of “testing.apk.aab”.
