Screen Time Limits activating prematurely

What is causing my screen time to bug? My mom set up social app limits at 3 hours per day (across all socials, not per app) but lately it’s been locking my apps after 3-30 minutes. If I turn off and turn my phone back on it fixes itself but it’s not a long term cure. I’m on an iPhone 15 from like a year or two ago and I’m on iOS26.2. Does anyone know what’s happening and how to permanently fix?
