3rd Party Plugin Presets Not Showing Up In Cubase Pro 10.5

I bought a plugin from Plugin Alliance recently and the presets aren’t showing up in Cubase.
They are however available in VE Pro. What is the story here?.

System specs? Wich plugin? Wich VST version?
Wher do you expect the presets?

Windows 10, Black Box HG-2MS, VST3, in the drop down on the plugin UI inside Cubase.
