I explain my problem in this video:

basically it put the tracked values into "motionblur.shutter angle" instead of "hotspot" aka position. It works fine with the normal LensFlare, but it's bugged with the s_lensflare (sapphire)
It's so frustrating because it almost works, the hotspot also has the position values -1.00, -1.00 to 1.00, 1.00. but I can't copy paste the values, which I shouldn't have to do in the first place, I should be able to select "SLensflare.Hotspot" instead of "Slensflare.Motion Blur.Shutter Angle".
