OK I figured out how to correct the title tags on the subsequent pages.
As they say "even a blind squirrel occassionally finds an acorn."
But for some reason the root app of the directory does not display different title tags for subsequent pages.
I have a feeling this can be fixed by editing a macro override?
I tried app_title_contents but the one in the directory is identical to the one in the forum (which works) so it can't be that one. I think.
