Problem - Owl Carousel doesn't show all slides (+ ui tabs)!?

Question

Owl Carousel

Hello! Such a problem. A wordpress site, it costs owl carousel + uitabs, everything works well, but for some reason it only shows the last 10 slide products, instead of the full number, there are about 20 of them in each of the tabs.
Link to the site where to look - goo.gl/eK6BUE (this is a block carousel on the main "Promotions, Budget, Copyright"). In js, adding the items and loop options doesn't work.
Link to code pen - goo.gl/SQ2dXJ
Please tell me how to solve it. Thanks in advance.

Answer 1

Found a solution. It was necessary - 'post_type' => 'products', 'posts_per_page' => -1,
'posts_per_page' => -1 - will display all products from the specified category
