Likely as a result of changes made for https://github.com/archivesspace/archivesspace/pull/1705 , the Rapid Data Entry Fill Column feature will no longer allow for fill values to be set for Basic Information - Level of Description. While it was only intended that Basic Information - Level of Description should be grayed out/disabled in the column visibility dropdown, the change has disabled this selection in multiple unintended drop-downs.
A Fill Column value (Basic, not Sequence) should be able to be set for Level of Description.
Discovered this one today, . Happy to chat more/screen share at your convenience to provide more context.
See pull request:
This appears to be fixed. I can apply a fill to the Level of Description column.
Tested on test site and this issue appears to be resolved.
