Wavelab cannot find Weiss MM-1 plugin

Hi. I’m on my new M4 Mac mini.
Having installed DAWs and plugins and all done but the Wavelab doesn’t seem like finding Softube’s Weiss MM-1 plugin while Protools, Logic and Cubase does.
It’s not on “Do Not Load the Following Plugins” list.
Thoughts?

There is an option to rescan plugins, try this.

Can’t believe I missed it.
Thanks.
