Ubuntu Software only shows apps installed in the current session NOT ALL installed apps

I don’t know how this has happened but I have just noticed that Ubuntu Software is only showing apps installed in the current session NOT ALL installed apps…

I have literally just done a clean install of Ubuntu 22.04 48hrs ago so, it really shouldn’t be broken.

Is there a way to fix this issue? I don’t want to have to reinstall my whole system again.

I found one post where someone had the same issue. No one resolved it.
