Duplicates in sample sets and participant sets
If you upload a participant set or sample set that has entities that already exist in the workspace, you end up with duplicates in the set. This makes it difficult to add additional entities to a set without generating a new metadata tsv. And if you make a mistake there is no way to delete the duplicates and you need to start over by creating a new set. The fact that you can have duplicate entities in a set, seems like a bug.
