PAYDAY 2: Why do I have multiple copies of it in my achievement list?

Hello all,

I actually just joined TrueSteamAchievements, but there is one problem that has concerned me: Why do I have multiple copies of Payday 2 and some other games in my achievement list?

I made this thread because maybe other people have the same problems. The reason why is that I don't want to be considered a cheater...

Anyways, if there is any way to remove the extra Payday 2's and the other extras, that would be great. I made the thread here just for that reason (and the reason that I don't cheat). I could redirect it if it doesn't fit, but I'm new here so...

Thanks everyone.

Sincerely,
Pr3Ci510n

It's prob just a coding mistake. Who knows
