Games not showing up in "Installed Games"

 My Steam account is linked to my EA account. I know they're linked because my Sims 4 and all packs that I've purchased on steam does show up in my EA app. I've purchased The Sims 2 Legacy Edition and The Sims 3 with a couple packs. However, my Sims 2 and Sims 3 are not showing up in my EA app? I've updated the app, unlinked and relinked my Steam account, restarted both apps and even tried restarting my computer. I'm not understanding why they're not showing up in my EA app and just want help fixing it. If you know how or have any other ideas on how to fix this please let me know.
