My UE Megaboom looks way different than yours

I received a warranty replacement UE Megaboom speaker a couple weeks ago from the manufacture. It showed up faulty and I am just now able to process the warranty claim again for a replacement. Before I had to disable it for replacement I opened it up and it looks completely different than all the photos on your site and on other sites. Could I possibly be missing parts or is this just an updated design?

Under the bottom cap there is no black plastic shield, just components. The charging Port is almost free-floating not supported or reinforced and directly is connected to the computer board.

My warrantee replacement had major malfunctions and never worked properly.
