Problems wrong weapons in game history

I’ve been noticing in game history weapons I haven’t used showing up. For example: A rocket launcher showed up with 2 kills and I never used a rocket launcher. I was standing next to the guy using it in Noctus firing it out the second floor of the base and got 2 kills with it. It showed up in my weapons used in game history. I’ve hardly ever used rocket launchers. In another game I picked up a Grav Hammer and killed 1 player and smashed a guy on a gun goose and only got I kill and didn’t get a medal for destroying the gun goose. I went to theater mode to see what happened and my gamer tag showed up which was odd because it was a GIP and I was viewing some else’s game play, it wasn’t me. I’ve noticed odd things happening since the last update. The number of games that I get dropped into have drastically increased. Almost every game I play is a game already in progress now. About 80 percent of the time the game is a loss without a chance of winning.
This is getting very frustrating… I only play warzone because I have handicaps and won’t ever be able to play competitive modes. So the K/D and all is not that important. I’ve tried all the new setting for search preference and there’s no difference. The only thing I’ve noticed is I haven’t got a disconnect yet, which I didn’t get very often before.
Also, some of the games in progress I get dropped into, the reqs I have available are only the loadouts… All the other reqs (mods, weapons, vehicles) are grayed out. Not fun when I have an AR and a BR and everyone else has power weapons and vehicles. Go hide in the core base and wait for the game to end after being slaughtered to no end.
