Why is software update saying I have an update but on most recent update

System Preference update is showing I need to UPDATE NOW for macOS Catalina Security Update 2021-007 10.15.7 and Safari 15.1. I've checked the About this Mac and it's 10.15.17 (19H1419) and Safari is 15.1. I've clicked the update now and the computer restarts and the black screen with Apple logo comes up. The gauge proceeds to maybe quarter inch and then no where, after hours computer restarts and System Preferences Update still showing I need to update. FRUSRATED!!

Lets see the output form the Terminal.app copy and paste:

softwareupdate --history
