Data Refresh Fails, Error message claims duplicate ID value in table

I have a PBIX file where when I go to refresh my data from a SQL server the refresh eventually fails with an error message that says one of my tables contains duplicate IDs. I went to my actual SQL DB and ran a query on the table for the exact ID provided by the error message. Only one row is returned by the straight query, therefore there are no duplicate values in my table.

I'm thinking this is some sort of red herring and that the real issue lies either in a relationship or somewhere else in the data. Any suggestions on how to troubleshoot? I've updated PowerBI to the latest released version.
