Manually editing TV shows or Movies

Back in 16 we could just press "i" and enter manually the dsecription or flush the bad search result. Now on 17 seems like when we do "i" on a episode it only force a new scrappe from the internet. Is there something I'm missing here? Where is gone the manual editing?

P.S. : I'm new here, dunno if I'm at the right place, and I don't usually speak english too >_<
