We don’t have option for it right now. To keep things simple we didn’t add this so far. Though modifying plugins file is not recommended but if you need it then try the following solution

Open ‘advanced-post-slider.php’ from plugin folder, go to line no around 514
look for the following code

minSlides: <?php echo $caro_ticker['advps_caro_slds']?>,

and replace the line with

minSlides: 1,

then add the following line of code just below the previous line

moveSlides: 1,
