ResolveFX plugins not working in Fusion

Hi I have my Sapphire Plugins working in Fusion but not the ResolveFX plugins.
Am I doing something wrong?
They show up in the effects library but all nodes come up red when applied.
Should they be working? I believe support was given to them in V15 b7?
Cheers
