Hi Funslinger,
Welcome to Apple Support Communities. Since this seems to impact the badge notifications specifically, make sure that Badges is enabled for your apps from Settings > Notifications > [App name]. Use notifications on your iPhone or iPad - Apple Support may be a helpful reference.
It might also be helpful to refresh your iPhone by restarting. Guidance below is from Restart your iPhone - Apple Support.
"How to restart your iPhone X, 11, 12, 13, or later
- Press and hold either volume button and the side button until the power-off slider appears.
- Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
- To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."
If the same continues, it may be best to reach out to Apple Support since badges may not be working as expected.
Take care.
