Unity 5.1.2f1 lens flare's fade speed doesn't work neither in light component option nor lighting settings, how do i get rid of this bug?

I’m using the lens flare free asset. I put the lens flare as a component in the lights, try to put directly in the light options but still have the same problem.
As i said i’m using Unity version is Unity 5.2.1f1.
Thanks in advance for your help.

Did you ever get this to work? I have the same issue, fade speed doesn’t work in the game (but it does appear to work in the editor).
