Почему Slick slider сбрасывает стили блока?

Question

[Даулет Даулет]

у меня на сайте есть tabs вкладки, при загрузке сайта самая первая вкладка с слайдером открывается нормально, но при переключении на другой tab slick slider теряет свои стили?

мой сайт https://cindustries.eu/ слайдер стоит на главной

код слайдера

<div class="tabs" role="tablist">
