How to set multiple blocks for a slide in Owl-carousel?

Question

Owl Carousel

I need it to turn out like this,


and it turns out like this



. Probably, this is because the .paint-block block is set to width: calc(100%/3), but if you remove it, then the block will simply move apart. How to set so that the blocks are scrolled one by one?

This gallery is located in the paint block
