For some time I have been seeing an “optics module ambiguity” icon in the upper right corner of the previews in the image browser of Photolab 7. This also means that the optical corrections are not automatically applied. Why is this and is there something I can do to get rid of the “ambiguity”?
Module ambiguities happen, when metadata aren’t good enough to determine, which module should be used. This is rare, but normal nevertheless.
To resolve an ambiguity, click on the “ambiguity” badge of the respective image in Library view and select the module that matches the shooting condition. If none of the proposed modules is an exact fit, consult Appareils supportés - DxO
Note that module ambiguity badges can be switched off and on in PhotoLab’s preferences/settings. For detailed info, consult the user guide:

Thank you. I wonder if this could have anything to do with the fact that I have previously been using the same lenses with another camera body?
When inspecting the metadata for the picture, it only says “70-300mm f/4-5.6”, not “Tamron 70-300mm f/4-5.6”, as I think it should. I also have another lens (NIKKOR) for which I don’t experience this problem.
Well, in that case you should have a separate camera-optic-module.
As @platypus recommended, “select the module that matches the shooting condition”.
If in doubt, take a screenshot/note and check out what’s going on with the other camera/lens combination. You can always delete the corresponding profile (restart PL with a folder that doesn’t contain any images with those lenses) to then assign the “new” profile.
Ambiguities exist because lens manufacturers use lens IDs that they have used before for a different lens or belonging to some other manufacturer. Third party manufacturers tend to help themselves by not using unique IDs - and difficult to do, unless manufacturers agreed on how to assure unique IDs for their lens models - worldwide.
Best practice: Work with what you have and don’t ask why unless you like answers expressing shrugs, dunnos and dontcares. Ask how to cope with issues instead.
