Data Asset is greyed out
Issue: When assigning Data Assets to an Asset Collection, some data assets are greyed out an unselectable.
Description: Data Assets can only be assigned to one Asset Collection at a time; those that are already assigned are greyed out.
Workaround:
Delete the Asset Collection the Data Asset belongs to, and re-create the Asset Collections with new assignments.
Create the Asset Collection without the unavaible Data Assets.
