Hi adkaminski,
Test after forcing the Settings app to close, as re-launching the app may resolve the issue. To do so, simply swipe up from the bottom of the screen, pause in the middle of the screen while swiping, and then swipe up on the Setting app to close it.
If the issue persists, then test the behavior after restarting your iPhone and after checking for an update to iOS, as taking these steps can help to clear up unexpected behavior the device may be experiencing. Check out those steps here:
Update your iPhone or iPad wirelessly
1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
Reach out to Apple Support directly to help investigate the issue if it continues. You can use the following link to reach out: Contact - Official Apple Support
Kind regards.
