Hello Suzanne698,
First double-check and see if your device is fully updated which ensures it's using the latest fixes/improvements available: Update iOS on iPhone - Apple Support
Then check to ensure the following setting is enabled: Settings > Privacy & Security > Focus > Messages. If it is already on turn it off for Messages here, wait 10 seconds, and then re-enable it.
If it persists enable 'Share Across Devices' at Settings > Focus. Then enable one of the default Focus states, like Do Not Disturb as an example. Wait a few seconds before turning the Focus off. You may then try checking with your contacts to see if they're still noticing it appearing. If so, try repeating the same steps with your other device (Mac/Apple Watch/iOS).
Cheers.
