Missing “Add to library” in context menu

I have Kodi 17 running on Windows 10 and I’m missing the “Add to Library” entry in the context menu. I have “Add to Favourite” and some other but not this one. Do I need a Add-on or do I have to change some settings to get it? I already installed Kodi new but no change.

Maybe somebody could help/instruct me.

Thnx FantaM
