I'm trying to add plugins to Audacity and have downloaded them directly from the website. All plugins are in the "Plugins" folder. When I go to manage and try to enable them they seem to not appear. When I go to new > select all > enable it will show that the files have been moved over (side note: the plugins that do show is just a handful. There should be like 90 per the site. I am using version 2.1.1
