Light Mix and Batch render- different colors

Hi
I’m using Batch Render to save the image automaticaly after render end. In preview using Light Mix I have righ colors and brightnes I seted manually but after batch render saving the images are much darker and without Ligh Select colors. :confused:

What can be the problem ?!!! Please help!

Could you show us an example of this? (expected result vs what you are getting)
Are you saving the LightMix render element, or just beauty?
