Testimonials are not visible

On my website www.elpablocs.be I have created 3 testimonials on the home page, but only 1 of them is visible. Can you fix this problem?

Hello there,

What will happen if you remove the below custom CSS code:


.owl-carousel .owl-item {
  float: none;
  display: inline-block;
}
.owl-wrapper {
  width: 100% !important;
  text-align: center;
}

Regards,
Kharis
