Hello,

I'm manipulating the columns in my LCA - the goal is to get rid of the "," (comma) in the column UDP PORT. So I'm creating columns PRIOR and AFTER using regexp column manipulation. See the table

As the final step I use the concatenate manipulation method to glue PRIOR and AFTER together to achieve the goal. However, I'm experiencing the "Error trapped: An item with the same key has already been added."

Is it a bug or can I do something better?
