Duplicate W2 Forms

I am retired and in 2018 received deferred compensation from my previous employer. 

This seems a little strange, but my previous employer mailed me five identical copies of my W2 form.  Each came in a separate envelope.  All of the boxes on each of the  W2's contain the same information.  The only difference between the W2's are in the employer use only box.  My question is should I be concerned.  All responses appreciated. Thank you
