The wikipedia api provides a section an id (1 upwards), it'd be nice if that would also be included.

I recently installed Kiwix 2.1.1 (2.1.4) on macOS 10.15.5. I loaded a Wikipedia (and only one), all went well.

Closed Kiwix. Re-opened it. Nothing in the list. Opened that same Wikipedia, it now shows twice in the list.
