I have a smart list that solely has type filtering to recurring (not tasks or habits). The task count is off. I looked and cannot see what this number might be. It does not add up to the completed number of recurrences, nor does it add up to the tasks + sub-tasks. In my mind the most obvious number is the count of tasks (in this case 10).
FWIW, you can also clearly see the date grouping bug here too. This is grouped “by date”, and yet nearly half of them are being incorrectly assigned “no date”.
