Problem with Reason 12 and Waves plugins

From the latest Horizon bundle, only the VST3 Waves plugins show up from A to L in Reason 12, no others. I have tried to reinstall the latest version of Reason 12 and Waves Central. Anyone?

Hi @yacco.vijn,

Welcome to the Waves Forum.

Please note that some Waves plugins exist only in certain components such as stereo or Mono.
This means if you are on a Mono Track you won’t be able to see plugins that support stereo-only components.

If you verified the above and a hard rescan in reason as per our site article does not solve the issue, please Contact Technical Support directly and they will gladly assist.
