My expansions are missing in the Sims 4

Try this: 

All on the Sims 4 will go under one picture in the 'My games' tab in Origin, try this:
- Go to the 'my games' tab in Origin.
- Hover over your 'The Sims 4'.
You'll see a little screen come up with an 'i' and a 'play/download/install' button.
- Click on the 'i', you'll get a different screen.
- Scroll a bit down and you'll see your expansions and other stuff.

And I think you have this bug:
