Unsupported Image Format macOS Big Sur DXO PL4


I keep getting the above message. However, if I move the images to another folder and reopen DXO, the images open fine. Out of a folder full images, some images have this message. All from the same camera and lens.

The OS is macOS Big Sur with all the latest updates. MacBook Pro 2019 15", 16GB RAM
DXO PL4, latest version with all updates.

Any help would be appreciated.
