Re-entrant do not update their front pannels! (1 exception, FP of a single re-entrant VI that is identified by clicking of icon in diagram).
This challenge is generally accomplished by using a VI template (VIT).
So...
1) Set your VI back to non-re-enttrant.
2) Call the VIT instead of the VI.
Every call to the VIT will create a new VI based on the VIT.
