They should, if you click on each you should see that they are upgrades.
I've looked through them and they are duplicates - I have 4 of each upgrade.
I'm pretty sure I found out what's going on. They are definitely duplicates, but...
If you open Tracker, load a turn, use it, then leave it open in the background until the next turn comes in, load it, and so on, you get the duplicates. Close Tracker, open it, and the duplicates go away.
So, even though they are duplicates it doesn't matter because it fixes itself.
