I don't see this one there, though I suppose I could be related to the one about no signal strength in the signal icons. This morning I had two signal icons, both without signal strength, and one apparently stale. I had an LTE and a 5G icon, and when I opened the app from the notification (there were two notifications, one empty and one populated - I've seen that before) it only showed LTE and WiFi. I threw away and reopened the app a couple times with no change, then used exit from the app menu and everything returned to normal when I reopened the app.
