Views_infinite_scroll not working I'm using Drupal 8 latest stable version: 8.5.x

I have 2 blocks (Upcoming events and Past events).

On Past events views infinite scroll is working with a button enabled providing the user ability to view more. It has many items and the module works as designed.

Same structure Upcoming events block returning only one upcoming event. When user clicks view more button the page is returning nothing and even the one item listed get disappeared. 

Ajax is enabled on both views, the only difference is that upcoming events is returning only one result.

How can i solve this?
Why don't you duplicate the view that works and just reconfigure the filter criteria to met your requirements?
