.... although you set up a filled addon folder --> restart minion.
From what I see it came, because minion doesn't refresh the UI after the setup with the wizard.
You can verify that, by settings are correct stored in minion.xml.
After the restart, UI should show what you configured.
I install addons also manually, means not only via minion. What can lead to that these addons are not updated by minion (because not registered in minion).
To solve this, minion offers over "minion settings" (not "options") the button "Reset AddOn detection", to update its registry.
