Unable to disable block inappropriate content/Content Restrictions

I've had content blockers on my phone for a bit with my girlfriend setting a password - I wanted to limit my use of certain apps and websites. I now want the content block off, I have set Web Content to be Unrestricted, however it simply doesn't work. Incognito browser is still not available and I can't use safari extensions. I have tried, logging in and out of iCloud, resetting all settings and turning off content restrictions on all my other devices. I'm not sure what else to do.
