Are you saying you have two .dop files for one raw file in the same folder? There should only be one .dop file per raw file no matter how many times you edit it. Does this happen often? Did you inadvertently copy in a second sidecar file for the same raw file from a different folder or computer? What version of PhotoLab are you using?
Ah. I think this is the problem.
I am using the Sony 7Riii with a 24-70 Sony Zeiss lens. HOWEVER, I am using an A-mount lens with one of the adapters. Several times, I’ve picked this lens, but each time I open the images made with this combination, the little orange icons are there indicating that they don’t recognize the camera-lens combo.
I just checked (PhotoLab 3 - Windows) with A7RIII raw files and 24-70 f/2.8 Sony Zeiss lens in A mount with an LA-EA3 adapter.
When opening the directory, I have to choose between: Tamron SP 24-70, Zeiss 24-70 SSM and Zeiss 24-70 SSM II. There is indeed an ambiguity at the start since the Exif probably do not allow to define which one is used.
Once the correct module has been downloaded, no problem exporting to the disk afterwards, including closing / reopening Photolab.
It would be interesting to check in the list of installed optical modules if several modules can correspond to this zoom.
A late postscript to this as I had the same problem as the OP and it might help someone else.
It seems that a DxO Lens module can also cover several variants within a ‘model’ designation. I had the modules installed both for the camera body and for the lens (both Canon) but was still getting this error when trying to export images. It turned out that I had to specify exactly which version of the lens it was (in this case IS / IS STM/ IS USM). Once I did that, everything seemed to become clear… so far.
