FCP 12 Effects parameters are missing from Inspector
In FCP 12 the parameters for all of my Effects plugins and the Effects themselves do not appear in the Inspector.
I am not sure if this happened exactly when I updated FCP 11.2 to FCP 12.0, but I believe that is when this situation arose. All Effects, including those built-in to FCP, are experiencing this. Of note, plugins for Titles, Generators and Transitions seem to be working normally in the Inspector.
