kaioss496 When you have packs purchased through both Steam and the EA App, you have to play the game through Steam. Trying to play though the App doesn't recognize the packs you bought through Steam. You can find more info on that here: [CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game | EA Forums - 11831673
And you should disable One Drive for TS4 and leave all files on your computer. The game does not work well or at all in most cases with the files on One Drive. You'll need to copy or move all the game related files to your computer somewhere that OneDrive doesn't sync before disabling OneDrive. You can find out how to find where the files are here: How to find your user folder – Crinrict's Sims 4 Help Blog and if you don't know not how to disable OneDrive you can find out more by scrolling down to the OneDrive section: [CURRENT ISSUE] Sims 4 saves/user content disappearing (PC) | EA Forums - 11838402
After you disable OneDrive then move them into the appropriate folders in your user folder on the computer.
Hope this helps.
Edited to add more info.
