Family Games Library:
If you’ve opted to only allow access to a subset of the account’s library, your account’s library will include a new group called Family Games. Family Games are the games you’ve chosen to remain accessible while in Family View.
In order to add and remove games from this list:
Log into the account.
Select the Family View icon.
Enter your Family View PIN to exit Family View.
Then, either:
Find the game in your Library and right-click on the game and click “Add to / Remove from Family Games”.
Or
Visit the Family tab within Settings and click “Family View” to run through the Family View wizard again. This will provide the option to add or remove games from your Family Games group. Once finished, to return to Family View select the Family View icon and confirm your choice.
