Remove Duplicate ISF

Somehow I managed to accidentally install duplicate ISF fx which now appear in ISF Sources/ in every category except Histogram Viewer.

How do I remove those duplicates from the file menu of ISF Sources?

(I also have FCPX not sure if that is part of it. But the ISFs don’t seem to work when I’m using FCPX.)

If you have duplicate ISF media in your /Library/Graphics you can go ahead and remove the duplicates. Or it could be possible that you installed them in your system /Library/Graphics and User /Library/Graphics
