Hey danielkaminski1, not sure if this will work for you, but I was able to get my iLok plug-ins to show up by doing the following:
1. Open Studio One 4
2. In the menu bar go to Help --> Open Settings Folder
3. Delete the Studio One 4 Settings Folder
4. Uninstall Studio One 4
5. Re-install Studio One 4
Then my plugins were scanned correctly. This was all after trying to reset blacklists and locations, so there still may be a Studio One 4 problem.
