The one that says Mcafee total protection is the latest upgrade , which is installed in your computer .
The reason for one computer getting the latest version and the other not should be glitch in the update.
However , if you uninstall and reinstall mcafee security center , you should be getting the latest version in the other computer even.
Thank you for your response. Following your suggestion, a quick uninstall and reinstall did bring both PCs to the same home screen.
