Hi there,
Simply make sure to name each items differently, Adobe has an issue where he thinks a different object with the same name is a different instance and will create the number of instances that he finds with the same name.
The first image is how you named all objects:

This second image is how I renamed all objects, then Acrobat Reader didn't duplicated the issue.

Hope this will help.
