Hi @clinic
Please try to change with this CSS. guten-MNO08q, guten-LpNvD0, guten-gmcXzA are your testimonial element ids on the first section. So it will only apply on that testimonials.
.guten-testimonials.guten-MNO08q .swiper-wrapper, .guten-testimonials.guten-LpNvD0 .swiper-wrapper, .guten-testimonials.guten-gmcXzA .swiper-wrapper {
align-items: stretch;
}
.guten-testimonials.guten-MNO08q .swiper-wrapper .swiper-slide, .guten-testimonials.guten-LpNvD0 .swiper-wrapper .swiper-slide, .guten-testimonials.guten-gmcXzA .swiper-wrapper .swiper-slide {
height: auto;
}
.guten-testimonials.guten-MNO08q .guten-testimonial-item, .guten-testimonials .testimonial-box, .guten-testimonials.guten-LpNvD0 .guten-testimonial-item, .guten-testimonials .testimonial-box, .guten-testimonials.guten-gmcXzA .guten-testimonial-item, .guten-testimonials .testimonial-box {
