"Dock" issue

[dadders6]

For a while now (6 months?) My dock shows 2 items in systems preferences (first screen shot). When I click on that, there is only 1 software update (2nd screenshot) when I click on that, it shows that I should update to Catalina (3rd screenshot). Why is the dock showing the number 2?. I do a restart occasionally, even a shut down occasionally, and that "2" is still there.

What happens if you quit System Preferences, remove System Preferences from the Dock and then start it up again?

"quit system preferences"? When I do the 'force quit applications' I don't see sys pref there. I tried removing it from the dock, then opened again, no change, still showing "2"
