Sims 3 games disappearing in Origin!

So in 2010 I bought the sims 3 late night, and in 2011 I bought the sims 3 world aventures, and they would both show up in Origin, but for some reason they are both gone but all the other games I have bought aren't. I've checked the billing information and there is no recolection of the game being purchased, nor is it showing up in my history, but they are both installed and working on my laptop? I don't know how to get them back into Origin! Please help! Thankyou! 🙂
