DxO PL 6 latest version- Preview and JPG output mismatch- export has a different exposure / tone curve?

When I process a RAW and save the jpg or tiff, I see exactly the same image in photolab when I look the RAW with settings applied and the jpg or tiff that has been saved from it.

Why would they look different ? They don’t in my case.
Fortunately, because if I process a raw, this is to get what I see when I export it as pixel image.

Can you elaborate ?
