Hi,

Do you mean about Penci Custom Slider ? If right, It's not a slider based on posts.

It's a custom slider doesn't based on posts - it helps some customers use a Custom Slider point to any custom links.

If you want to use sliders based on posts, please use another slider style. If you're using Elementor or WPBakery to config your homepage, you can use Element "Penci Featured Slider" to get sliders based on posts.

Best Regards,
