I've had a look on your profile and all the other Steam trackers are seeing exactly the same thing as Exophase. If you have played free-to-play/family-shared games, you lose the license for those games after 2 weeks. You have to re-open them for trackers to be able to see them.
Only if there are missing games. Based on what I see on your profile on Steam, it looks like it's showing the same list of games, so I don't think anything is missing.
If nothing was showing after you changed privacy settings - that's normal, we don't constantly check profiles to see if they changed privacy, only once a day. There is an option to run a manual scan to pick up the changes instantly. It's recommended to run that if you just changed privacy settings.
