Slider Incorrect On Mobile

Link to my site: https://myancientwisdom.com/

The slider works great on my desktop version.
However, when I view it on any mobile device some strange things are going on.
First the pictures are very narrow horizontally and cut off the majority of each photo.

Next, the call to action button is either missing or cut off in two of the three photos.

Lastly, the second photo (the green leaf) is missing the words that are supposed to slide in. How can I fix these things?
