Collectible Guns

[Nitro]

Hi all, playing through GF BC Camapign and I have noticed that my trackers aren't accurate.

 

I have collected all the guns in the first level but yet the game says I stil have 1 collactible left on this map.

 

Any idea on why this is happening? I tried deleting my save and restarting the game, but it still happened.

Not that I think it should make a difference, but I am playing on Hard using the guide on PSNP

Depending on the difficulty if your playing hard or normal the guns are already track if found it on your 1st play there aren't hard to track check under collectibles should give what your missing...
