Excerpt not showing on smaller screens

The slider works fine on the computer and iPad mini in landscape orientation. But when I rotate the iPad mini into portrait orientation, the excerpts are gone. And the excerpts do not show at all on the iPhone in either orientation.

This is my site: https://www.fujidreams.com

Note, all of the images are 1140 x 445 but three of them are white where the excerpt would be. That is just part of the image.
