sims 3 not installed but still saying play on origin

A few months ago I installed The Sims 3 from my mac to free up space for Sims 4. Since then I have decided to reinstall but instead of there being an install option on origin it instead says play. I have been through every forum on the topic and have done a manual uninstall. I have removed every file that mentions the Sims 3, have uninstalled the origin installer multiple times and restarted my computer yet it still says play! 

Someone help me please!
