Difference between in game compendum and social club

[gamerfan1010]

Has anyone else noticed a difference between what shows in the game progress in the compendum and what shows when logging into the social club? For example, in the game, under weapons it shows me having the pirate sword, tomahawk, and other weapons but it doesn’t in social club-and I’m trying to get everything in the game so I’m confused as to why the 2 don’t match up

Maybe they haven't updated the social club in a while? It has been quite some time since I checked either. I might check them tonight to see what differences are on my lists.
