Still searching why this second instance of exposure set to +3ev which ruins my work and seems impossible to remove.
The manual does not tell much about this - but maybe is it because I do not search in the right section.
I am going to continue searching, with the hope that I will find where this second instance comes from - and why +3ev ? In my initial workflow, exposure is set to 0. So, again, why this value seeming come out of the hat ?
