The the thumbnail and details would be from same slide, the JA ACM slideshow style is designed in this way.
If you wan to hide the completely you can use this code in /css/custom.css file
.slideshow .swiper-thumbs-wraper {
display: none;
}
If you want to details part and want to remove only thumbnail use this code
.slideshow .swiper-thumbs-wraper .swiper-thumbs .item-image {
display: none;
}
And If you want to keep the Active item thumbnail and details as in your screenshot, Use this code in custom.css file
.slideshow .swiper-slide-active .swiper-thumbs .item-image {display:block!important
It will look like this : http://prntscr.com/k5k09a
You can choose any option 🙂
