Joiner shows column results multiple times

guys, Hello I am just getting into KNIME and have run across a joiner issue that I can’t seem to solve with Google. The results are duplicating the last column Total Receipts Dollars but they are unique by SKU in my original data. In the expected results screenshot I used the Group by node but when I go to join it with the desired table it duplicates again. I am not sure if that makes sense but thanks for the time. I have added the results received, results workflow, results received setup, and Expected results in screenshots.
