Thank you for contacting Toolset support. I see you are trying to show posts in a slider. There are images missing on the page if we check console and slider is also not showing any images. Can you please add the images?
I am checking the structure of the slider and settings in the meantime..
The slider should only be showing featured images from user's cred posts. It looks like it's picking up other pictures as well? Right now there are only two cred posts on the site.
It is displaying featured images from user's cred posts correctly. Actually I had created Test posts for checking slider arrows. Now I have removed test posts.
I've also assigned a sample featured images to one of your existing post, you can change the featured image.
