iTunes doesn’t show anymore downloaded status of apps
 

After I bought an app in iTunes, on the small tab beside the app, instead of the price showing 0.99, or whatever the price was, it used to say 'downloaded'.
This was helpful, so I knew right away which app I have bought and which I haven't, so I wouldn't need to download it again.

But now, it doesn't show this anymore. That little price tab shows only the price of the app, no matter if I already bought it or not. So if I forget that I already downloaded a certain app, I have to download it again (not pay for it, but anyway I waste my time and my monthly GB Internet usage).

What I did was, I just pressed the 'reset iTunes store cache' and 'reset all dialog warnings', from Edit/Preferences/Advanced Preferences, starting from the Edit tab of the iTunes.

What can I do now, to have again the specification 'downloaded' on the little tab of the already bought apps?

This is an iTunes issue rather than one for these forums, but I would check in your purchased section on iTunes.
