Please Help I'm Going round in circles here

I bought a couple of new add-ons in Sims 4 but they didn't show up in my game. I have lots of packs and ad ons so I downloaded them in exactly the same way as before, nothing new. I went through numerous processes from forums and you tube videos etc and got nowhere. In the end I uninstalled the game, EA and steam. I then reinstalled steam, downloaded the base game from Steam (where I originally got it) and reinstalled the EA App. It all looked promising and I went ahead and downloaded all my packs etc. Nothing but base game is showing up when I play. I can see all the folders for the ad ons like EP01. EP02 etc in Windows-Program Files-EA Games - The Sims 4-

I do have an Electronic Arts folder here as well though, as you see below EA Games there is a folder Electronic Arts. I also have an eletronic arts folder in My Documents.

I've literally wasted two days of my life trying to fix this and I've spent a fortune on packs and ad ons. I hope someone can help
