shell:AppFolder not updating / incomplete.

[VoxCodice]

I configured a custom shell using the guide from the link below to launch a WPF app as shell and the shell launcher park works a treat, my WPF app being launched without a fault. https://github.com/Microsoft/Windows-iotcore-samples/blob/develop/Samples/ShellLauncherV2/SampleBridgeWmiScripts/README.md

The problem I am now facing is that the shell:AppsFolder does not list every installed app on the system as it would if I were not using a custom shell. If I undo my changes and revert to explorer, the shell:AppsFolder is populated correctly. If I configure my WPF back as a shell replacement, the shell:AppsFolder is again incomplete.

When installing or removing an app, the shell:AppsFolder would normaly update almost immediately. When using a custom shell, the AppsFolder doesn't change.

Must I configure Shell Launcher V2 differently to fix this issue?

Below is my current configuration:
