I can't seem to delete unwanted tracks when I have the "Include Missing NLA" button selected. What bothers me more is it seems to create tracks by random. In the screen shot below, 1/4 lights have an NLA track, my camera has an NLA track, the Mesh Body that is attached to my Armature has an NLA track and the armature itself has an NLA track. Also the eyeballs have one. This seems very random, where do these tracks come from? Why are they so random? Is it possible to clean them up?
