Slick slider not syncing on mobile but good in desktop

Hi,

We have this problem in mobile when we click on the actual slider, it won’t show as the main picture however, the slider next to it will. For example, see this screenshot: https://prnt.sc/u6wzz4. I was clicking the white bed but the red bed shows as the main picture. I was not using a plugin, I am using slick js from this documentation. https://kenwheeler.github.io/slick/. This is the site link. https://franksalt.com.mt/properties/712957

Please help as I don’t where to get answers.

Thank you,
Mariah
