The only list I could find is this and there is no season at all, do you have an official source for the seasons?

https://www.thetvdb.com/series/quarks/allseasons/official Here there is a season for every year. But it's no official source. All episodes in one season is very confusing (for me).

every database has different rules, here we want to have the official listing and I'm honest I can't find one, so maybe someone will do in future

Hello, I was just having a look at fixing this show here. In fact, the "semi-official" is directly in the ARD mediathek, which is not consistent as they delete old episodes often and there are short videos (excerpts from full shows) in between. My personal Opinion: Either we should use 1 Season, but then not actually call it 1993, or we should do it by year. Having all episodes in one Season called "1993" is definitely wrong, no?

One Season is okay, someone added more seasons with null episodes so I deleted them now all missing episodes can be added to season 1

OK perfect, thank you very much!

Sorry for bothering again. I just noticed that e.g. Terra X does actually use a season for each year. For that show there is also no "official" ordering. Why can't it be done for this show?

There's no decision about Terra X for now, there are many Terra X Miniseries added and the one for all episodes but as I said we are not sure about how to handle it
