DNGs exported from DxO PureRAW are linear DNGs, which means they are already demosaiced. Therefore in DxO PhotoLab they show the "no module available" icon and the tooltip says "some corrections are not available with linear DNGs." However, that's not a problem as those corrections have already been applied to the file. If necessary to change the corrections, please go to back to the original RAW file and either use DxO PureRAW or DxO PhotoLab.
