OLD FCPX PLUGINS WON'T DELETE!!??

I have manually deleted a ton of demos and plug ins I no longer want.. then reset the preferences on FCPX but for the love of god!!!!! I can still see the plug ins .....in their previous generators, effects or titles browsers... not only that but when I go into the directory manually on my mac... they wont go - I have tried dragging them into the trash and deleting them - 

Is there a workround?

Did you quit FCP before trying to manually delete them?

plugins from FXFactory have to de-installed with/in its own fxfactory.app

I did quit yes, and I can see them coming back as I open the application. 

They are not FX - they are others. 

V odd. 

You're may be seeing the Motion projects that the plugins were wrapped in. These usually reside inside of folders here:

~/Movies/Motion Templates/Effects/
~/Movies/Motion Templates/Generators/
~/Movies/Motion Templates/Titles/
~/Movies/Motion Templates/Transitions/

But I've also seen some get placed in the Final Cut Pro template folder in the Application Support folder in /Library

/Library/Application Support/Final Cut Pro/Templates/Effects/
/Library/Application Support/Final Cut Pro/Templates/Generators/
/Library/Application Support/Final Cut Pro/Templates/Titles/
/Library/Application Support/Final Cut Pro/Templates/Transitions/
