Every time I try to modify an "obscure" effect with the mouse when there is another one on the sampe clip the changes affects both of them, in order to have them separated I have to modify the parameters manually 

Reproducible: Always

Steps to Reproduce:
1.Apply an obscure effect on a clip
2.Apply a second obscure effect on the same clip
3.try to modify one of them with the mouse

Actual Results:  
this operation changes both the effects

Expected Results:  
only the selected effect is changed

I actually tried this on the 16.04 version from the testing ppa and the 16.07 version from the master ppa with the same result
