iMac Fusion drive showing incorrectly in import panel

Hi all

Has anyone else had the following issue using the fusion drive in a 2019 iMac and Catalina.

The Drive shows correctly in the Library Panel of Lightroom Classic but when I click to import photos and videos the display changes to show the "Macintosh HD - data" image of the drive and not the "Macintosh HD" image I should see and which my photos are located in the library. If I right-click the disk and select show in finder the finder window does not show the drive and the display has reverted to the top level drive list. I have tried an uninstall and re-installation but the problem continues.

Thanks for any help

David
