Now in the GF it display the last value a second time, can I avoid that?
"Last value" refers to the last record in the group?
ie: given a group with the codes
I'm guessing since you used suppression, you now have duplicate records in your group which you do not want to record.
I guess in this scenario, you could initialize an array in the GH and then add values to it from the details. You would check whether the current code exists in the array or not, and then add it if it doesn't.
This will ensure that you have an array with unique values. You can then construct a string from the array in your display formula.
