Quickdraw contour files not loading on 73DV and 93SV chartplotters

Hi All- New forum member here.

I downloaded a Quickdraw contour .qcc file from the Garmiin Connect site and tried to load it in both my chartplotters.  One of which is an older 73DV and the other a slightly newer 93SV.  Both have the latest updates installed and work perfectly otherwise.  The .qcc file was downloaded to a macbook pro and moved to a new SD card that was formatted in FAT32 and placed in a folder named Garmin.

Both units display the same message when I try to load the file: "Quickdraw Contours community content install failure".  Does anyone have any ideas on how to troubleshoot this or ideas on what the problem could be?

TIA,
