Guys I did get it sorted! Do not fret! I had to contact Xbox support via the speak with a gamer chat function, you escalate the case and they call you back! It’s a glitch in the system that reverts your profile to child.
you have to change settings on Microsoft and add a ghost lead family organiser (with a different email to your account), you then have to add your problem account to the family group and then you change Xbox settings. It’s a really crappy process but it did work eventually. Took me 6 days to get fixed
