Exclamation point icon on some of my RAW photos... but why?

(See screenshot) I’m baffled, really. These files are available, but you can’t use much of any Photolab editing on them. Why don’t they work?dxo%20photolab%20exclamation%20points

Did you check if the camera is in the support list?
And the lens too?
This ! Is for when camera or lens isn’t supported by optical module.
Which camera and lens is in metadata of the rawfile?
