Unfortunately, Debloater application is not working as it previously was because the developed didn't update the source code. The new phones and Android operating systems had their Security Policy updated as well and Debloater doesn't work with them, therefore an update is needed. I tried to use Debloater on my phone with Android 7.0.1 and it displays only two APK files that are not related to the files stored in the /data folder on the system partition.
I strongly advise avoiding using Debloater anymore. If you want, install Titanium Backup and manually remove the apps you don't need.
