Hi Psuedolb_99,
Thank you for contacting Apple Support Communities. Based on what you stated, it seems like you want to remove someone from the family group. I would recommend you use this article to help troubleshoot the issue.
The family organizer can remove anyone over the age of 13* from the family group. If you need to, you can transfer a child to another family.
*Age varies by country or region.

- Go to Settings > [your name] > Family Sharing. If you're using iOS 10.2 or earlier, go to Settings > iCloud > Family.
- Tap the name of the family member that you want to remove.
- Tap Remove."
Leave Family Sharing
If you forgot your Apple ID password
Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.
Cheers.
