Question

My Waves plugins are in the proper path, but do not show up the Plugin Manager. How do I correct this?

Answer 1

Do you have the 3rd party VST support add-on installed for Studio One Artist?  Studio One 4 Artist requires an add-on to use 3rd party VST plugins.  Studio One 5 Artist does not require the add-on.

If you do have the VST support add-on installed, did you check the box to scan your plugin folders on start up so Studio One can find your plugins?
