Can’t install store worlds

I bought all the world from the EA Store when they were half off and redeemed them in the Sims 3 Store.

The worlds show up in the download section of the launcher, and every time I try to install them. It says installation was successful, but it doesn’t show up in the install section of the launcher. Only worlds that actually installed were hidden springs and roaring heights

I tried installing the worlds in the main menu and in-game, but it doesn’t work. Instead, it just duplicates the flies

I tried to repair the game through EA, but it still doesn’t do anything. Any way to fix it?
