Spooky stuff pack has installedbut the Sims 4 game says it is still installing

So the left is what origin says ( I hit the play button as seen from spooky stuff), the right hand side is what appears (I never receive a notification.
Also if you see at the bottom left - origin says its installed.
I've also re-installed origin and repeated all the above comments.

Sorry for the grainy photo on the right, my computer would not screenshot it.
