Oh, I think you're talking about the difference between the stats page here and the medals list in the game?
The stats page has an incomplete and inaccurate medal list. This has always been the case and it has never been corrected. The game's counts are mostly accurate and should always be trusted over anything you see on the site stats. Do not expect ND to fix these problems.
Also, do not trust the Tricky Boy or Shade Survivalist totals either in the game or on the site. Achieving either contributes to both counts. If you were playing before the Shade medals were introduced, your Tricky Boy count from that period was reset when the "technical hooks" for Shade Survival were patched in.
In short, these are long known issues that you should never expect to be addressed.
