How to filter a View by Year and Month with Summaries for each one
You can override the parameters in each individual display.
I'm not sure about D8, but in D7, the "display order" of the displays was important as well, such that you'd get the behavior of the higher priority display (lower display order) as desired. In D7, I had to go into the database itself, and change the "position" of these pages in the "views_display" table. (I know of no way to do this in the UI.)
