SOUTH CHINA SEA - Collectibles

I noticed a bug on Battlelog which shows the following collectibles for the SOUTH CHINA SEA mission:

Weapons found 3/4

Dog tags found 3/3

The problem is in game the collectibles for that mission are as followed:

Weapons found 3/3

Dog tags found 3/3

Which mean Battlelog made up a Weapon Collectible.

PS: As for in game yes, I also have the swimming glitch in this mission (used to work fine last time I played it).
