I'm not completely sure I understand what you mean by "sharing the profile" but that may be the way Family Sharing is designed to work if you enabled these option:
How to share purchases with your family - Apple Support
When you turn on purchase sharing, everyone in your family gets access to apps, music, movies, TV shows, and books that family members buy. The family organizer is billed for family members' purchases.
Share iCloud+ with your family - Apple Support
With Family Sharing, you can share a subscription to iCloud+ with everyone in your family group. When you share an iCloud+ subscription, everyone in the family group uses their own account. That way your photos, documents, and other information stay private, even though you're sharing access to the service. You simply share the features and space available in iCloud+ with your family members, so you only have one plan to manage.
