Discord: winutil.exe file does not work with -Config

Discord: .igrokit: Purchased and downloaded the winutil.exe file. My intention is to use it repetitively with an exported config (json file).
This works (starting in an Administrator window):
PS C:\temp\winutil> & ([ScriptBlock]::Create((irm “https://christitus.com/win”))) -Config “C:\temp\winutil\test.json” -Run -NoUI

This does not work (starting in an Administrator window):
.\winutil.exe -Config “C:\temp\winutil\test.json” -Run -NoUI

What happens here is that it asks for the Administrator shell and then starts the GUI. But the settings from test.json are not loaded

the content of test.json:
[
“WPFTweaksRestorePoint”
]

Is this intentional or is it a bug?
