This is the official page of the original network. Episodes should be listed as per this page.

No, these pages aren't official and shouldn't be used to determine episodes numbering.

The original network has decided to number this episode inside the normal season. So, we are doing the same.

Ok, I understand your problem to decide what is the original. But if you handle it in this way, please switch back "Frühling from ZDF (German tv) to a TvShow. (I wrote it in an other thread) This is describt as Series in the description by ZDF

another moderator is in the process of clarifying this and they will answer then
