6 Episodes???

Dating myself here but TV series used to be have 26 episodes in a season, then 26 weeks of reruns and then the new season started. Streaming shows have gone down to 10 episodes and in some cases 8 but this is the first show I've seen with only SIX episodes in a season. And now a 1-2 year wait for more. If these shows are profitable ( and I assume they are if they're being renewed) does it really take that long to film a single episode? It's hard to call 6 episodes a "season."
