How to get the right text/label for choices with the same recoded values

Hi, My Survey contains a dropdown list question with a lot of products for which I added recoded values (kcal). Some of the products have the same amount of calories and thus recoded value. When I export my test data as csv file (use choice text) and then read this file in R, I still want to be able to distinguish the products that have the same values. However, when I look at the data in R, it doesn't show the product/label that I selected but it seems to just pick one of the products with the same recoded value. How can I fix this? I hope you can help me, Kind regards Loes
