The SubmissionListColumn entity table has a combined unique constraint of "title", "predicate", "input_type_id".

There are two issues:

1. the modals for selecting submission list columns or custom filters has unidentifiable duplicate titles
2. the multi-column sort in the admin submission list view has a bug as it is using submission column title as a unique property

A simple solution would be to make title a unique constraint. This would correct all known bugs regarding.

A more versatile solution would be to provide the predicate in the label for the submission list column such as ORCID (dc.creator.orcid). This would require fixing the bug in the multi-column sort to utilize the combined label for uniqueness. Would still have edge cases to where title and predicate are unique with a different input_type_id.
