Update changed my phone restrictions by itself.

Im 16, and have the correct age set to my phone. There are restrictions on my phone by our family manager set to 17+, but since I updated my phone with the latest update, it set my age rating to 9+?? Our family planner hasn’t changed anything, and it’s not like I’ve done anything to warrant such action. It deleted a bunch of harmless apps, and we don’t know what’s going on. This happen to anyone else?
