HALion Sonic 2 and HALion 5 released

I have question.

In Halion Sonic 2 Multirack, when you are selecting VSTs, ratings there is category and sub category. When you click on either one it gives you the option to select a different category you want the VST to be in and it also gives you the option the select none. WHen you select none the VST disappears. Where does it go to? Because when when I type it in search I cannot find it. I selected none by accident. How do I get it to return?
