Blocked from retrieving older backups on Time Machine

I just had to do a fresh re-install of Mojave OS (10.14.6). My goal is to retrieve files from an older backup on my Time Machine.

I'm using a WD My Passport for Mac external hard drive.

When I enter Time Machine, the various backups mount from last year. The Time Machine correctly recognises the last date saved. However I cannot advance with the arrows to an older backup to retrieve a file or anything.

Is there a security barrier? Since I re-created my administrator account, do I have to override something?

Any guidance would be most appreciated.

Time Machine is great when it works, not so much when it doesn't.
