15v4 beta random brightness

I exported my color corrected short film shot on Ursa Mini 4k everything looked great. Noticed a dark shot so I went back and brightened it up in one of the nodes for that shot only. Went to re-export it again and found that my entire timeline was overexposed. All settings are the same. Cannot for the life of me get it back. All the stills are fine but if I reapply the grade it still shows too bright.

It sound like you added a grade to a timeline node, so the whole timeline has that addition.
