Red dot showing in the software update icon but already updated to Catalina 10.15.4

Red dot showing in the software update icon but I have already updated to Catalina 10.15.4. When I click on it it says "your mac is up to date". but the the red dot won't go away. I restarted the computer as well and it still won't go away. All App updates have been done as well.

Mac Mini late 2014 - 3 GHz Dual-Core Intel Core i7.
