DaVinci Resolve Video AI Plug-in doesn't do anything?

Windows 11
DaVinci Resolve 18.6
Video AI Plug-In installed

When I drag the Video AI Enhancement FX onto my clip on the timeline, bring up inspector, set to Proteus and Auto, then hit play on my timeline I see no difference at all?

I tried a Quick export on a marked section of my clip with Topaz FX and the export is identical to the original?

Thoughts/Suggestions?

Cheers, Rob.
