CC desktop app doesn’t offer older versions of Photoshop and Lightroom

Creative Cloud desktop app doesn’t offer older versions of Photoshop and Lightroom
I have spent several hours researching this matter online various Adobe help articles and Adobe community posts and still can’t resolve this issue.
Had drive failure, starting from scratch, don’t want to use migration assistant.
Working as expected.
MacBook Pro Mojave - Although using latest Photoshop and Lightroom apps, Creative Cloud Desktop app offers ‘other’ versions of Photoshop and Lightroom by clicking on three horizontal dots.
Not working as expected.
Mac Pro 2008 El Capitan V10.11.6 clean HD install - Creative Cloud app doesn’t offer ‘older’ versions of Photoshop and Lightroom with pref ‘show older apps’ activated. Clicking on three vertical dots only shows ‘Learn More’, please see attached screen grabs.
I have uninstalled Creative Cloud desktop App and from my online Adobe account reinstalled.
In my Adobe account (after several failed attempts to get CC desktop app to show older apps) I deactivated My Mac Pro to see if this would clear the issue.
I have two up to date duplicate backups of the main HD before it crashed which do allow older app versions, maybe this was because CC desktop app was an older version?
Any help most appreciated.
