I am having some challenges with Featured Images showing up on a Page but not a Post  -for example the following pages

https://swhr.org/swhr-interdisciplinary-network-on-alzheimers-disease/and https://swhr.org/swhr-interdisciplinary-network-on-sleep/ 

 The featured images do not show up on these pages The featured image does show up on the post pages. 

The featured image is not showing.   What settings do I need to use to be able to see  it.
