MultiRack not showing registered plugin

I am fairly new to Waves and am having an issue. I have waves central and multitrack installed on my PC. I have several plugins install and activated, but when I try to add a plugin to a rack, it shows that “NO PLUGINS AVAILABLE”

What am I missing? These are all plugins that I have used in Studio One (same account) but they are not being recognized in MultiRack.

Any help would be appreciated.

What version are your plugins? V13?
V9 are the last version of Plugins to be supported while using MultiRack (Replaced by SuperRack).
If your also using servers on a newer system you have to roll them back as well.
