Why are only some of my plug-ins showing up in Logic?

Please perform a Full Audio Unit Reset of your plug-ins in Logic's Plug-In Manager.

1. Choose Logic Pro > Preferences > Plug-In Manager.
   
   
   
   
2. Click Full Audio Unit Reset.
   
   
   
   
3. Close Logic Pro, then reopen it. Logic Pro rescans all installed Audio Units plug-ins.
