If this information is not updating, you can try restarting your iPhone. That step is known to help when we encounter unexpected issues with our devices.
1. Press and hold either volume button and the side button until the power off slider appears.
2. Drag the slider and wait about 30 seconds.
3. Press and hold the side button until the Apple logo appears to power it back on. Once back on, test to see if this continues.

Have a good one!
