Is there a way to resolve a list of references in a view without cloning entire rows of data?
Depending on how you want to use the results of the query, you could use a GROUPBY option within the Views config.
Find the GROUPING options by clicking on the word "Settings" under FORMAT. The link for "Settings" appears to the right of the pipe symbol which separates the chosen format from the "Settings" link.
Once you do this, it should remove the duplicates.
