Various Izotope DX plugins that have been uninstalled still show up in V15. I have:

Uninstalled ALL Izotope plugins. Then deleted all Izotope folders in various places. Deleted all registry entries for Izotope. Followed detailed instructions from Izotope tech support to delete everything.

Deleted the vegas cache files then started Vegas 15 with cntl-shift to delete cached data. Uninstalled V15 and reinstalled the very latest update.

Uninstalled VST plugs are gone. Various Izotope DX plugins still show up in V15, NOT in V14 or V13.

WHERE are these listed? How can they be deleted?
