"No DxO Optics Module is applied on exported image"

When I hover over a Jpeg image on the bottom of the Customize window the text “No DxO Optics Module is applied on exported image” shows. What on earth is this? Was the optics module applied when the image was exported or not?
DxO PhotoLab 3, version 3.0.2 build 24.
When I look at the list of downloaded modules I have all the necessary modules.

Hello @Bjoran,

Module was applied on your image when it was exported.
The message concerned exported image (the processed one). We don’t allow to apply correction from the lens correction module on images already processed in PhotoLab as it can make them applied twice wich has no sense.

Thank you @Marie, now I understand.
