RSS option forever (only delete entries manually)

When having an RSS feed you can select to keep the data for 1 day, 1 week etc, but you can also select 'forever (only delete entries manually). The forever part is working like a charm. The delete entries manually part I’m not able to find at all? Anyone any clues or able to explain how this should work?

Thanks a million.

Anyone tried it with 8.5.4 yet?
