I also ran into some issues in LUNA with Helix Native and all of my other 3rd Party Plugins. No audio would process through the plugin until I turned off the Toggle ARM Mode feature (icon looks like a target) in the Global section in the Transport area. Clicking on the yellow target icon will make it gray and it will then be turned off. The plugins will not be displayed in the plugin list if the "ARM" feature in engaged.
If you follow those steps you should be good to go…
1. Add a new Audio track
2. Click on + for Inserts
3. Add an instance of Helix Native
4. Make sure Toggle ARM Mode is Off
5. Pass audio
